I’ve skipped a few episodes in Colin Conway’s excellent The 509 series of police procedurals. That was because The Only Death That Matters became available free. But they’re stand-alones, so it was all right. I enjoyed this book just as much as its predecessors.

Ray Christy is a police volunteer. He’s 72 and an army vet. Every day he visits his wife, who’s in a care facility for memory loss. His only son became a cop and died in the line of duty; Ray volunteered to help the Spokane police in an effort to understand his son’s commitment. He doesn’t carry a badge or a gun; he does routine work to take pressure off the real cops. It fills his time and gives his days a purpose.

One day he’s called to pick up a “found” item, a woman’s wallet found in a parking lot. On a whim, he decides to take it back to the owner, at the address on the ID. But when he gets there, he learns the woman is dead, drowned in a bathtub. This is a group home for the elderly, and the owner treats him rudely. Surprisingly, that owner is a cop.

Ray is immediately suspicious. He starts doing research on the man and his business dealings. And then everything blows up…

The 509 series, set in eastern Washington state, is a top-rank mystery series, in this reader’s view. Emphasis is heavily on character. The people in the story are faceted and relatable; I wanted to see how things worked out for them. Detectives Quinn and Burkett are here again, welcome like old friends.

The Only Death That Matters is highly recommended.
