After being shot, Alden finds himself at a monastery, where a monk befriends him. Noticing a stained glass window of St. Anthony resembles him closely, they set out to find the artist who did it.

Anthony is lured to a strange apartment by a naval officer, where he finds a girl in a harem costume. Later he's accused of murdering the officer by the police when his body is found in a room where his finger prints are found.

A reluctant girl is used as a medium in a magic act, and a blue coronet is part of her costume. This intrigues Mike and Tony, who find the magician a strange and probably psychotic devil worshiper who won't let the girl go.

Alden hears a pop tune on the radio, supposedly from a dead singer, yet never released until that moment-but he somehow knows the lyrics already, and surmises that he had to have been present at the recording session. Tony joins him as they pressure the dead star's producer for information.
