A dead body forced inside the top of a funerary urn - on the lawn of a remote country manor - with a toy llama carefully balanced on its head.A few days later, the body of a woman is found, tied to a gothic-style chair with her throat slashed. There's a llama with her too.The two victims were part of the 'Famous Four', a group of friends who studied at the University of East Anglia back in the day. Three of them still work there. And now two are dead.The team's new DCI, Helen Hudson, is convinced the prime suspect is Dom Wilkins, a member of the Famous Four and one of the victims' old flames.Sara worries she's overlooking something obvious. And she has a growing suspicion that her boyfriend is keeping something from her. Sara must keep focused if she's to unmask the killer before they strike again.
