Quirky, lovelorn Inspector Broekstein is back, this time in a mystery that begins with a random bar of soap on a factory assembly line and a simple message carved on one side: Help me.

A peculiar situation turns into something much more sinister when Broekstein learns that his female coworkers are being threatened and stalked. The war is over, and someone apparently does not want them working on the line anymore.

All is not as it seems, however, and Broekstein will need to keep his wits about him if he is to solve a dangerous case of infidelity, misogyny, and vengeance-without losing his head or his heart in the process.
