Book recommendations for stories about old unsolved murders getting solved

[Alex]

Looking for books that revisit old unsolved murder mysteries and solve them. Can be fiction or nonfiction, can be paranormal. Thanks for any suggestions to come!

The Daughter of Time by Josephine Tey is a classic. It's part of a series but probably could be read as a stand-alone.

[The Reading Raccoon]

Have you tried any of Sue Grafton’s books? Her main character is a private detective and she’s hired to solve a lot of different cases. Some of them are pretty “cold”. I’m thinking of Q Is For Quarry in particular.

Nemesis, by Agatha Christie. It's a sequel to another book, but it definitely stands alone. Nemesis

I'll Be Gone in the Dark: One Woman's Obsessive Search for the Golden State Killer is a good non fiction read. Sadly the author passed away while working on the book but it's worth googling more recent developments in the case after you read it.

There are two cold cases involving missing girls in Case Histories (fiction).

Portrait of a Killer: Jack the Ripper - Case Closed by Patricia Cornwell - at least it's her theory on the case.

The Family Vault by Charlotte MacLeod The Family Vault

[Ann aka Iftcan]

Real Murders (not totally sure this is one, but it came to mind.)

Grave Sight this is a series. The MC is able to "feel" bodies in the ground as a result of a lightning strike that she survived. I'm not totally sure how many of the 4 books in the series have your theme, but I know that the last one has them solving the central mystery of the MC and her adopted brother/manager/husband/protector.

The Julius House this one has the MC solving the disappearance (and murder) of an entire family that happened years earlier.
