When Mark Howitt strikes lucky on a Friday night in Glasgow, he expects a fun, no-strings night of passion with Leila. But when he wakes up in the early hours of the morning and tries to find the exit to Leila's flat, he is horrified to stumble upon his former bed partner dead and suspended from the ceiling of the next room, alongside twenty-seven Barbie dolls.
Rhona Macleod's forensic investigation of the scene reveals the cord used to hang Leila to be a cingulum, an artefact used in the practise of Wicca, and sketches hidden in nine of the dolls suggest the dolls are linked with nine men, and as the investigation continues, it looks increasingly likely that other wiccan witches will be targeted too.
Helping with the investigation is the newly demoted DI Michael McNab, who is desperate to stay sober and not disgrace himself further. But an encounter with Leila's colleague and fellow Wiccan Shannon threatens to throw his plans out the window. Soon, McNab realises Shannon may hold the key to uncovering who the killer is and identifying the nine men linked to the dolls. If he can get to her before the killer does . . .
