Amazon’s Editor’s Picks: Best Mystery, Thriller & Suspense for April, 2026
If any of the titles garnered starred reviews in the four library journals, that is indicated after the plot summary of the title. Amazon does a good job of coming up with these monthly lists and especially its year-end best list.
This month’s list contains five debut novels and several novels by authors I have hitherto been unacquainted with. MAD MABEL by Sally Hepworth looks like my kind of book. There are only two of the picks that got starred reviews, pretty light for an amazon monthly picks list. I was surprised that Tana French’s THE KEEPER didn’t get any starred reviews. One of my favorite authors, Jane Harper, has her latest, LAST ONE OUT, coming out this month. I was disappointed by its lack of pace.
Novels that I would have put on my list of Best of April are: GUNNER by Alan Parks, THE MONK by Tim Sullivan, A DEADLY EPISODE by Anthony Horowitz, ONE SECOND AWAY by Rick Mofina, and the debut THE ENDING WRITES ITSELF by Evelyn Clarke (Library Journal Starred Review).

Amazon Editor’s Picks: Best Mystery, Thriller & Suspense – April, 2026
MAD MABEL, Sally Hepworth (St. Martin’s, $29.00, April). Meet Elsie Mabel Fitzpatrick: eighty-one years old, gloriously grumpy, fiercely independent, and never without a hot cup of tea―or a cutting remark. She minds her own business in her quiet Melbourne suburb, until a neighbor turns up dead and the whispers start flying. Because Elsie hasn’t always been Elsie. Once upon a headline, she was Mad Mabel Waller―Australia’s youngest convicted murderer. But was she really mad, or just misunderstood? Either way, she’s kept her secret buried for decades.

NOTHING TASTES AS GOOD, Luke Dumas (Atria, $29.00, March). Retail worker Emmett Truesdale has never fit the Southern California mold of six-pack, suntanned masculinity. Over three hundred pounds, he carries the weight of his childhood trauma and millennial ennui around his waist and in his soul. After trying every diet under the sun, he remains stuck—in his dead-end job, in love, and in his body. Desperate for help, he enrolls in a clinical trial for a new weight loss product called Obexity. The treatment is as horrifying as the results are miraculous and as Emmett sheds pounds at superhuman speed, every part of his life improves overnight. Unfortunately, Obexity comes with some killer side effects, including lost stretches of time and overwhelming cravings. Worse, people who were cruel to him have started disappearing and when the police warn of a cannibalistic killer on the loose, he fears that Obexity is turning him into a monster.
