The Chalk Circle Man

When blue chalk circles begin to appear on the pavement in neighborhoods around Paris, Commissaire Adamsberg is alone in thinking that they are far from amusing. As he studies each new circle and the increasingly bizarre objects they contain – empty beer cans, four trombones, a pigeon's foot, a doll's head – he senses the cruelty that lies within whoever is responsible.

And when a circle is discovered with decidedly less banal contents – a woman with her throat slashed – Adamsberg knows that this is just the beginning.
