When a dead body is fished out of Glasgow’s River Clyde the morning after an office celebration, it looks like a case of accidental death. But an anonymous telephone call and a forensic toxicology test give Detective Chief Inspector William Lorimer reason to think otherwise. Probing deeper into the life and business of the deceased accountant, a seemingly upright member of the community, Lorimer finds only more unanswered questions.

What is the secret his widow seems to be concealing? Was the international accounting firm facing financial difficulties? What has become of the dead man’s protégé who has disappeared in New York? And when another employee is found dead in her riverside flat these questions become much more disturbing. Lorimer must cope not only with deceptions from the firm, but also with suspicions from those far closer to home . . .
