When Rachel Murdock and her sister Jennifer receive a call for help from their favourite niece, Lilly, in Breakers Beach, CA, they quickly hop on a train from Los Angeles to see her - but not before collecting their prized cat Samantha in a picnic basket and bringing her along for the ride. Samatha, it turns out, is an heiress, the inheritor of a fortune left by a wealthy relative and so the attempt at the cat's life, made right after they arrive, comes as a shock. The cat survives but unfortunately, Lilly, murdered soon thereafter, is not so lucky.

By the time the police arrive the clues are already falling into place. The source of Lilly's trouble is revealed to be a gambling debt incurred during an attempt to cheat at bridge and the suspects in her slaying quickly pile up. But then another corpse is discovered, buried in the nearby sand, and it becomes clear that the killing spree concerns more than just the young lady's personal money trouble. With the authorities distracted by lurid details, it's up to Rachel and her furry friend to uncover the subtleties containing the solution to the puzzle.

A prototypical early "cat mystery" written before the subgenre became a staple of cozy mystery fiction, The Cat Saw Murder is an entertaining and endlessly surprising whodunit with a focus on felines. Reissued for the first time in over half a decade, the book, written pseudonymously by the author better known for her hardboiled and suspense novels, is the first in the long-running Rachel Murdock series.
