On his rounds, a young police constable encounters a drunken young man late one night. The man tells him he saw a door opened and closed by a cat, so after the man leaves, the constable goes ahead checking doors and finds the door to a bookstore open. When he looks into the store, he finds a man shot to death in the office. It’s Richard Dodsley, the owner.
Inspector Mallet’s team finds that someone, possibly two people, waited in the store while Dodsley was out and shot him when he returned late to work on a sale catalog. They also learn that a mystery was recently published by Margery Grafton, the daughter of a prominent politician, the circumstances of which closely match those of the murder. It seems more than a coincidence that Margery Grafton is keeping company with Dick Dodsley, the dead man’s nephew, who worked in the shop.
The police find that Dodsley hired a private investigator, MacNab, to find out who has been stealing rare books from his store. MacNab has not been successful, but he gets more closely involved when Margery Grafton hires him to find the murderer because she thinks the police suspect Dick.
Death of Mr. Dodsley does not present us with a super-complicated puzzle , which is a point in its favor. On the other hand, characterization isn’t super important and there are a few important characters that we see almost nothing of, such as Dick Dodsley, the prime suspect. MacNab himself is a fairly laid-back character, and at times the plot seems to be moving very slowly.
Although it’s possible to guess the murderer, there is a surprise at the end that I didn’t see coming. It’s also fun that British Library has been lately publishing these “bibliomysteries.”
I received this book from the publisher in exchange for a free and fair review.

Skimming your review of this one, since I haven’t read it yet and hope to get to it soon. But I’m glad to see that you enjoyed it!
I’m liking these bibliomysteries.
I love the BLCC series! I’ve not read this one (I’m only able to collect them slowly and a few at a time) but I love the “bibliomystery” idea!
Yes, that’s nice. I also love the covers of the ones based on old travel posters.
I’ve enjoyed some of the British Library’s bibliomysteries recently too. This sounds like another good one, even if the characters weren’t great.
I’ve liked all the bibliomysteries to some extent.
