Kosuke Kindaichi comes to remote Onikobe expecting a peaceful mountain retreat, but finds death stalking him at every turn. No sooner has the famous sleuth learnt of a decades-old murder haunting the village than a new series of killings strikes the community.

This time the victims’ bodies are eerily arranged to allude to the lyrics of a children’s song. As the scruffy sleuth investigates, the murders continue, with a sinister, stooped old woman appearing before every new death.

Kindaichi must unravel a tangled tale of broken hearts and blackmail to get to the truth. Can he do so before the killer reaches the final verse?
