The relative peace and tranquillity of 44 Scotland Street is about to be disrupted. Irene is to return for a two-month stay, consigning Bertie to a summer camp. Not satisfied with that, she somehow manages to come between the enigmatic nun, Sister Maria-Fiore dei Fiori di Montagna, and her friend, the hagiographer, Antonia Collie. Can a person really change, even after being struck by lightning? Bruce's metamorphosis and new-found outlook on life is put to the test as he prepares to leave his creature comforts for the monastic simplicity of Pluscarden Abbey. His house sitter, meanwhile, gets a little too comfortable in his new life and discovers that the talented Bruce Anderson's shoes are all too easy to slip into. With great taste comes great responsibility.
