Miss Withers investigates a man who appears to have hanged himself while driving

As snow falls on the steps of the New York Public Library; a line of cars moves sluggishly down Fifth Avenue. Oblivious to the traffic, a blue Chrysler roadster tears down the street, hops the curb, and slams to a halt. The car is empty, its driver thrown half a block back. He is stone dead, his cigarette still burning, and a noose tied tight around his neck.

First on the scene is Detective Oscar Piper, followed closely by Hildegarde Withers, a schoolmarm with more than a passing interest in crime. They are a close-knit pair, and would have been married by now if murder didn’t keep getting in the way. Piper and Miss Withers must race across New York, attempting to learn how a man can be hanged while driving, and to do whatever it takes to keep his twin from suffering the same fate.

Murder on Wheels is part of the Hildegarde Withers Mysteries series, which also includes The Penguin Pool Murder and Murder on the Blackboard.
