Archie attends the will reading for a former business associate, Harry Grant, who owed him several thousand pounds. Almost all of Harry's money is to be left to his beloved cats, annoying his ex-wife Liz, son Hugo and young Irish widow Maria. Archie believes that Harry hid some stolen diamonds before he died but none of the interested parties claim to know of their whereabouts. A visit to sham medium Vlad the Impostor gives Archie a clue that the diamonds were "worn by girls." Harry referred to his cats as his girls and the one he loved most died recently and was buried in a graveyard. Maria recalls that Harry may have buried the cat in a diamond-studded collar, so everyone rushes to be the first to get to the cat's last resting place.
