In a house like Gulls Nest, curiosity might prove fatal . . .

After thirty years in a convent, Nora Breen has thrown off her habit. Her fellow sister Frieda has gone missing and it's up to Nora to find her. Nora's only clue is that Frieda was last seen at Gulls Nest boarding house. So she travels down to the seaside town of Gore-on-Sea, takes a room and settles in to watch and listen. Over dubious - and sometimes downright inedible - dinners, Nora gathers evidence about the other lodgers. At long last, she has found an outlet for her powers of observation and, well, nosiness.

When one of the lodgers is found dead, Nora decides she must find the murderer. Not least because she suspects the victim knew Frieda. Could solving this mystery help her to understand what has happened to her friend?
