The Sixth Catrin Sayer Mystery. Detective Inspector Catrin Sayer now leads art investigation within the prestigious Art and Antiques Unit of the London Metropolitan Police. Her team is suddenly assigned to assist Trident, the organized crime unit, at a crime scene in East London where a valuable painting has been discovered. It is a suspicious death; a young woman has fallen from the balcony of an apartment owned by a gang leader. The painting has links to a drug gang in Glasgow where, some years earlier, Sayer was part of an investigation that led to the imprisonment of its leaders. Now she is sent to Scotland to conduct interviews of the gang leader and his accountant, with instructions to ‘stir them up a bit’. She does; and it has surprising consequences.
