A manor house cosy crime with all the hallmarks of an Agatha Christie-style murder mystery.

Devon, 1929. Members of the Pedhurst and de Reve families gather to hear unpopular matriarch Julia Pedhurst (nee de Reve) read from her late husband's will.

One of the house guests is fighter pilot Fred Willets, now an inspector in the Kalgoorlie Gold Squad, who has come to the UK as a beneficiary of the will. When Julia dies before the reading, and another death follows soon after, everybody in the manor house is a possible suspect.

It is up to Willets, assisted by the bright young pharmacist Prudence Meadows, to crack this whodunnit.
