With a Vengeance: Jen’s Quick Take

- With a Vengeance is historical fiction, set in the 1950s, and on a train
- It’s a locked room mystery, with a small group trapped together
- With a Vengeance has definite Agatha Christie vibes, like Murder on the Orient Express crossed with And Then There Were None
- It’s a revenge story (as many And Then There Were None stories are)
- Readers are VERY divided. Right now the Goodreads ratings are low (3.5.)
- Some people embraced the vibe and enjoyed the book.
- Others found it slow-paced, repetitive, and implausible.
- I can actually see both sides. Is it plausible to invite all your enemies to an island and murder them? No, but it’s DRAMATIC.
- The 1950s train vibe was fun, and reminded me of Hitchcock’s North by Northwest. The plot also had All My Sons by Arthur Miller vibes for me.
- To me, this was not his strongest book. Just to help you compare your taste and mine, I think The Only One Left is by far his best book, and Middle of the Night is probably second. (I do like the quirkier ones.)
- Fun fact: this is only Sager’s second book written in third person. Do you know what the other one was?? Tell me in comments!
- I didn’t dislike With a Vengeance but probably could have waited for a library copy instead of buying it.
- Publication date: June 10, 2025 by Dutton Books.
