Perfect for fans of T.J. Klune, Becky Albertalli, and David Levithan, this hilarious, big-hearted LGBTQ+ mystery follows an unlucky in love—and life—gay relationship blogger who teams up with a take-charge lesbian and a fiesty bull terrier to find a missing go-go boy and bring down an international crime ring.
When Hayden McCall’s new crush suddenly disappears, the twenty-something gay ginger relationship blogger and middle-school teacher teams up with a take charge butch lesbian, a gentle giant, and a feisty bull terrier to find the missing guy.
Driven by a belief that the police won’t take the crime seriously, the improbable crime fighters prove that friendship — fueled by a lot of caffeine — has the power to bring down a diabolic international crime ring.

Prior to Devil’s Chew Toy, Rob Osler’s short story, Analogue, which was published in Ellery Queen Mystery Magazine, won the Mystery Writers of America Robert L Fish Award as part of the 2022 Annual Edgar Awards. Rob lives in California with his long-time partner and a tall gray cat.

Interview:
On writing:
How did you do research for your book?
As DEVIL’S CHEW TOY is a contemporary novel set in a city I’m extremely familiar with, there was not a heavy research task. Also, because the two main characters are VERY amateur sleuths, I could avoid needing to get a lot of police procedure right—though there is some police interaction. That said, it’s amazing how many little questions arise in every chapter that require a pause and some desk research.
Which was the hardest character to write? The easiest?
The hardest character to write was Hollister—not that she was too challenging. I strove to be respectful of Hollister’s identity as a Black lesbian in America without going so deeply into her character that hers became a story that wasn’t mine to tell.
The easiest character to write was Hayden McCall. Why? Because there’s a whole lot of me in him. We are both naturally shy and smaller of stature (though he’s shorter and slighter). I took Hayden on the type of adventure—with a bolder, stronger, and more courageous friend—that I would love to go on.
There are many cozy mysteries out there….What makes yours different?
My story features two extremely amateur sleuths, one mild-mannered gay ginger and one butch lesbian. I’ve heard from some reviewers and readers that while pairing a gay and a lesbian as the main protagonists is not unprecedented it is uncommon. Also, I intentionally wrote a story in which the queer characters are neither the villains nor the tragic victims.
What advice would you give budding writers?
Understand that whatever amount of patience you have will be depleted and then some. Publishing moves in increments of months. It takes a long time—and a lot of collaborators—to bring a book to market.
Your book is set in Seattle. Have you ever been there?
I set the book in Seattle because it’s my “Spirit City.” I lived there for nearly twenty years and loved it. Given as much time as it takes to write a book, I wanted to return to Seattle and its neighborhoods and hills and waterways during the long writing process.
Do you have another profession besides writing?
I have been a marketing and branding strategist for many decades, both at agency/consultancies and at technology corporations. I think the general mind set of prioritizing activities that matter most has helped me with all aspects of writing and the navigating the publishing process.
How long have you been writing?
I actually started my professional career as advertising copywriter writing television commercials for Kellogg’s and Tropicana and Procter & Gamble. Fiction writing also uses words to communicate but that’s about the only commonality I’ve found! It’s the difference between landing one memorable message versus telling a compelling, captivating story over three hundred-plus pages. Trust me, a novel is way harder.
Do you ever get writer’s block? What helps you overcome it?
You know, I really never do. But then I’m not much of a procrastinator either—not that they’re the same thing. My biggest challenge is going off on a tangent with a character or a scene that needlessly complicates the story and “writes me into a corner.” I do a lot revisions.
What is your next project?
I have recently sold my second short story to Ellery Queen Mystery Magazine. It features a fifty-something cross-dressing whacky amateur sleuth named Perry Winkle who solves a murder at his Palm Springs condo community.
What genre do you write and why?
I write traditional mysteries because that has been the genre I have always most loved to read. And I feature LGBTQ+ main characters because I am gay and we need more books—of all genres—that represent the great and glorious rainbow of humanity.
What is the last great book you’ve read?
Two spring to mind. The first: THE SAVAGE KIND by John Copenhaver, who also happens to be a very nice human being. This novel—no surprise—won the Lambda Literary Award for best mystery this year. The second: DEAD LETTERS FROM PARADISE by Ann McMan is sheer delight. Both books are truly terrific.
What is a favorite compliment you have received on your writing?
“I can’t wait to read the next one!”
How are you similar to or different from your lead character?
Both Hayden and I are gay, mild-mannered, quiet, but good for an occasionally humorous one-liner. We both play tennis and enjoy big personalities. As Hayden says, “we balance each other out.”
If your book were made into a movie, who would star in the leading roles?
The characters are so distinct in my head, I can’t picture a known movie star playing either Hayden, Hollister or Burley. However, I can see Della Rupert, the oddball proprietress of Barkingham Palace, played superbly by Melissa McCarthy.
If your book were made into a movie, what songs would be on the soundtrack?
Stanley Kellogg’s “Falling Hard,” of course! This song, which was made up along with the new country star himself, reoccurs throughout the story. Fun fact! After the book was published, a good friend, Ben Davis, and I completed the lyrics and Ben wrote the music and produced the track. It’s on my website. Check it out!
What were the biggest rewards with writing your book?
Hearing from readers that they enjoyed it.
In one sentence, what was the road to publishing like?
Long.
What is one piece of advice you would give to an aspiring author?
Every time you are certain you’re done working on a book, know that you aren’t.
Which authors inspired you to write?
Agatha Christie and Armistead Maupin.
What is something you had to cut from your book that you wish you could have kept?
There’s a line that 91-year-old Jerry delivers in reply to Hayden’s question: “How did you get to be so wise old man?” Over the whistle of the kettle, Jerry replies, “I managed to live a long damn time.” That “damn” was an Eff-bomb until the final edit. It was the only strong swear word in the book. By removing it the book avoided an R rating, if you will. But I still love the idea of Jerry saying the line with more gusto!
On rituals:
Do you snack while writing? Favorite snack?
No snacking. But I do try to drink plenty of water.
Where do you write?
I have a home office. I’ve never been able to do the coffee shop thing. I am too easily distracted.
Do you write every day?
Not every day. But I do write most days.
What is your writing schedule?
I usually write in two- to three-hour spurts. In a mystery, context and pacing is so important I am not skilled enough to dipping in and out.
Is there a specific ritualistic thing you do during your writing time?
Nope. I just plop my butt down and starting tap, tap, tapping. I will say I find it very difficult to stop writing before I finish a chapter, even in the roughest draft form.
In today’s tech savvy world, most writers use a computer or laptop. Have you ever written parts of your book on paper?
No. But I do use notebook paper to scribble plot ideas before I write.
Fun stuff:
If you could go back in time, where would you go?
The seventies. The music was awesome. Though I’m still wary of bell bottom pants.
Favorite travel spot?
Switzerland.
Favorite dessert?
Raspberry rhubarb pie
If you were stuck on a deserted island, which 3 books would you want with you?
The Mouse and the Motorcycle
Tales of the City
All the Light We Cannot See
What’s the most courageous thing you’ve ever done?
I set off for Alaska to work on fish processing barge after my sophomore year at college. If fish were running, the shift was 16 hours, every day until all the fish were processed. I still don’t know why I did it, but I returned two more summers.
Any hobbies? or Name a quirky thing you like to do.
I have been life-long tennis player and watcher. I can usually name the top twenty men players—and often in order!
If there is one thing you want readers to remember about you, what would it be?
Rob Osler writes traditional mysteries featuring LGBTQ+ main characters.
What is something you’ve learned about yourself during the pandemic?
We are social creatures who need human interaction.
What TV series are you currently binge watching?
Inventing Anna by Shonda Rhimes on Netflix.
What is your theme song?
“Sultans of Swing” by Dire Straits.
What song is currently playing on a loop in your head?
“The Seaside” by The Lazy Eyes
What is something that made you laugh recently?
Jinx Monsoon’s roast performance on RuPaul’s Drag Race. Hi-lar-ious.
What is your go-to breakfast item?
Toast and yogurt with berries.
What is the oldest item of clothing you own?
I have a green argyle sweater I bought in Seattle thrift store about forty years ago.
Tell us about your longest friendship.
Twin girls, Kelly and Shelly. I grew up with them. We went to elementary, middle school, high school and then to the same out-of-state college! Just a few months back, I did a book event at the wonderful Boise bookshop Rediscovered Books. Guess who was in the front row?
Who was your childhood celebrity crush?
Willy Ames who played the role of Tommy on Eight is Enough.
My thoughts: this is a very funny book. I loved Hayden and Hollister, the world’s most ridiculous PIs, in their very recognisable car, hunting for their missing friend, ably assisted by the excellent Burley (who bakes, this book made me hungry!)
The characters are great fun, the plot completely bonkers at times and there’s an adorable dog in the mix too. It reminded me of How I Paid For College by Marc Acito (one of my favourite books) and several other highly entertaining capers I’ve read. I really want more of Hayden and Hollister solving crimes and getting in way too deep with things that are maybe best left to actual law enforcement.
