Do plots involving exchanged murders still work and who exactly is the victim? Antonia Darcy never imagined that taking her young grandson to his first day at nursery school would embroil her in a most baffling case of mistaken identity and murder. Major Payne, on the other hand, believed that it was their destiny. Olga Klimt played a dangerous game with the affections of the men in love with her, though she knew perfectly well there might be a high price to pay ? Among the unlikely murder suspects is a rich young heir to a biscuit fortune, his Aconite-addicted mother, his manservant and the headmistress of a prestigious nursery school. In this, their ninth investigation, husband and wife sleuths, Antonia Darcy and Major Payne, search desperately for answers before the killer strikes again.
