If your August is filled with peak summer heat, I hope you’re in a blizzard of cold air conditioning so your detective cap doesn’t melt off your head. Grab a cold drink and get ready to read some great mystery and thrillers publishing this month that will have you glued to the page, and hopefully distract you from the heat for a bit.

I know there’s a lot of talk about anticipated fall books but let me tell you: the end of summer 2024 has some gems, including a great standalone from the author of the Truly Devious series. You can also find plenty of popular tropes and subgenres from middle grade to adult novels to keep you armchair sleuthing through the end of summer! There is a PI novel set in Chicago with a complicated case; a luxury resort wedding murder; an Australian missing person mystery; a suspense novel centering an influencer; a delightful middle grade series; a British procedural with a fictional serial killer; a YA novel starring the daughter of a PI; a dual POV missing person suspense, and a true crime memoir!

And if you prefer/also like backlist titles, there are plenty of those recommended throughout too!

Death at Morning House by Maureen Johnson

In the 1920s, physician Phillip Ralston adopts six children from England during the war and raises them in a mansion with strict exercise and studies based on his eugenic beliefs. Then, his youngest biological child is found dead, and an older sibling falls to her death shortly after.

In the present, Marlowe Wexler has a disastrous date that literally burns down a house, so she absolutely takes the opportunity to go stay on an island for a summer job. But while the fire she was in was an accident and everyone was unharmed, she is about to be in real danger: the house on the island was the home of a family with an unsolved murder mystery, and people are always willing to murder to keep secrets hidden…

All the Way Gone (Detective Annalisa Vega #4) by Joanna Schaffhausen

For fans of prime-time procedurals, thrillers, and cops turned PIs!

Annalisa Vega was a cop who solved serial killer cases (start of the series) and is now a PI. Her first case is complicated: author Mara Delaney wrote a book defending the idea that good sociopaths exist, including Dr. Canning, a Chicago neurosurgeon. But when a woman dies in Canning’s building, Delaney starts to think he’s not the kind of sociopath she can defend, and Vega discovers the dead woman was disliked enough by multiple people for this to not be an easy murder case.

Never Saw Me Coming: How I Outsmarted the FBI and the Entire Banking System—and Pocketed $40 Million by Tanya Smith

For fans of nonviolent true crime memoirs!

Tanya Smith grew up in Minneapolis where her love of Michael Jackson in the ’70s—and trying to get his address—led her to discover a way to scam people: being passed enough times through the phone company’s departments would make it look like you were calling from the phone company. This taught her the art of a con and she spent two years scheming to get to Michael Jackson, including as a child getting on an airplane to fly out to L.A..

Then, as a teen, she became a little Robin Hood: using her phone con to learn how much money people she knew had in the bank, she pretended to work for the phone company in order to void people’s utility bills by claiming the person had just paid her in person. The cons only grew from there, leading to her learning the computer and banking systems. By the time the police caught up to her they didn’t think they had the “mastermind” and wanted to find whoever was the real brains behind the operation. Even in prison you could say she was unstoppable—she escaped twice!
