Wealthy widow Charlotte Hendrick had always promised that her riches would be divided equally between her seven closest relatives when she died. Now she has changed her mind and summoned her nearest and dearest, including her cousin, the Reverend Mother, to her substantial home on Bachelor's Quay to inform them of her decision. As Mrs Hendrick's relatives desperately make their case to retain a share of her wealth, riots break out on the quays outside as the flood waters rise ...

The following morning, a body is discovered in the master bedroom, its throat cut. Could there be a connection to the riots of the night before - or does the killer lie closer to home? In her efforts to uncover the truth, the Reverend Mother unearths a tale of greed, cruelty, forbidden passion ... and cold-blooded malice.
