Plot

Ex-detective inspector (DI) Frank Hathaway, now a debt-laden private investigator, meets Luella Shakespeare when she employs him to investigate the fiancé she met online. Hathaway and his assistant Sebastian Brudenell discover that the fiancé is a con man. They report back to Luella, but she is reassured by her fiancé, and the wedding occurs. When her new husband is killed at the reception, Luella is suspected of murder by local DI Christina Marlowe, who had been Frank's junior. Luella is thrown together with Frank and Sebastian to crack the mystery of what has happened, and after her name is cleared, she uses her recovered savings to buy into Frank's business. Their only employee, Sebastian Brudenell, is a young aspiring RADA-trained actor who uses his skills when undercover investigations are required. He lives above a theatre costumier run by Gloria Fonteyn.
