Killer Couples: Deadly Duos and Their Horrifying Deeds

by Charlotte Greig, John Marlowe, Paul Roland

Murder and crime are not always a solo affair. Sometimes, when one is confronted by the horrifying truth of their partner's evil deeds, rather than recoiling in horror, they instead join in on the carnage. In other times, it is the love of evil that brings them together, and they share in monstrous fantasies that they enact on the world. Covering up each other's crimes, they can prove difficult to catch.

4 stars.
True crime stories about 34 couples dating back to the early 1830's to the early 2000's. Some crazy stuff and even more crazy it's likely true.

4.25 ⭐️ This book had a lot of people and cases that I haven’t heard about. I thought it was a good look at most of the cases although a few had very little information. I do wish that some of them had more info. It also is a book that won’t tell you every single thing about the couple, but it’s a good overview of the case. It’s easy to read since it’s broken up by case, and it is in chronological order roughly.
