Book Summary

Adorable oddball couple Jane and Simon take a private detective class and must use their (admittedly limited) skills to solve a series of mysterious disappearances in this delightful debut mystery.

Jane Pye and Simon Mash are a millennial couple with a little extra time on their hands. Jane was recently let go from her position as a back-end programmer, having never been quite sure what that meant. And Simon's career as a corporate collaboration consultant seems to be less collaborating and more scrolling the internet in search of matching velour tracksuits and well-balanced charcuterie boards. When they sign up for a private detective class on a whim, they quickly realize they've bitten off more than they can chew.

Their instructor, having a feeling his two worst students don't have a chance of solving anything beyond finding the classroom, assigns them the case of Nellie Thorne, a woman recently reported missing. But she's not the first Nellie Thorne to disappear. In fact, she's the fifth in fifty years. Jane and Simon set out to solve the case, armed with just a few days of notes, matching trench coats, and a feeling they should have enrolled in a different class. The investigation leads the newly minted Pie and Mash Detective Agency to places they never thought they'd go, including haunted woods, mysterious archives, and, most terrifyingly for Jane, Simon's mum's house.

As clues emerge, more questions than answers begin to pile up. What links the missing Nellies? Why do locals think she's a ghost? Is their teacher hiding something? So what if they're heavy on heart but light on experience. Jane and Simon are determined to uncover the truth in time to pass the class and save the day.

Would be detectives?
It took me awhile to adapt to the pace of this story. Once I did I found the theme fascinating and I quickly read it straight through. The two authors seem to work well together and hopefully will follow with a second in a series.

Mary L. (Greeley, CO)

Quirky, amusing mystery
The reader first encounters unemployed Jane and her neurodivergent boyfriend Simon. Jane has decided they should take a course which will teach them to become private detectives, so off they go on the Level 1 class, taught my a semi-retired detective Gavin. The final project of Level 1 is to go after a case of Dev's missing girlfriend. It is a case Gavin deems unsolvable and the reader soon learns over 20 years before Gavin had investigated a case of a missing woman of the same name as Dev's girlfriend. Off the reader goes as Jane and Simon encounter a mysterious partially buried red candle and a cast of kooky people, including Simon's mother. A secret Gavin has kept from them throws another shock into Jane and Simon's world. Any lover of mysteries will want to go for a "ride along" with this excellent story.

Delightfully Quirky Debut
The Pie & Mash Detective Agency is a delightfully quirky debut by a duo of writers using the pseudonym J.D. Brinkworth. Unemployed Jane encourages her partner, Simon, to enroll in a course learning how to develop skills to investigate crimes, missing persons, cheating partners. The duo are assigned to investigate an old case that remains unsolved by their instructor. What happened to Nellie Thorne?

Replete with equally appealing eccentric protagonists and peripheral characters, I believe a cozy mystery series could be successful.

Sam S. (Bedford, TX)

Great Cozy Detective Mystery by Author Duo
I thoroughly enjoyed this cozy comfort read, particularly around the holidays when I want a book that's interesting enough to keep me turning the pages, but relaxed enough to allow me to unwind.

The plot is well conceived and develops organically. I was dying to know how the story was going to end and once I got there, everything made sense and left me satisfied despite the big "answer" not being what I thought it would be. That being said, it wasn't anxiety-inducing as some thrillers or mysteries can be.

The characters are very personable and I felt the authors excellently wove in aspects of modern culture. The writing style provides a sense that you could be hearing a wild tale from a friend you haven't seen in a while. There is quite a bit of British slang that I had to look up while reading but I take that as a bonus since I learned a few new things as well.

I did not know until I finished the book that the author is actually an author duo. This doesn't change my opinion of the story at all but I enjoy the blend of creative energy that it brings to the table (or, the shelf?)

Can't think of anything negative to say about the book, it was an easy and solid 5 stars for me. If there is a sequel, I will definitely be reading.

A cozy mystery with a fun duo
Enter two wannabe detectives into an old case of missing women....sounds good. The two are quirky and mostly likable as they fumble their way through the investigation. Some details about them were irrelevant and made me like the writing a little less. Felt a little forced. All in all, it was generally an entertaining story.

Debbie_C

Mystery and discovery
Although this book started off slowly, it soon gained momentum. The characters are charmingly romantic, adventurous, and a bit quirky. During their detective training, they developed their own unique techniques that ultimately helped crack the case. Pie and Mash make an excellent team. I hope there will be another book with their adventures.
