When Philip reaches his twenties, he has already received letters from Ambrose explaining he has married Rachel, a cousin of theirs. The letters become grimmer as he describes he doesn’t feel well. Philip travels to the villa in Italy to check upon his guardian, but discovers Ambrose died and Rachel has left.

He suspects Rachel must have poisoned Ambrose but as they meet in England, Philip falls in love with her while simultaneously trying to discover what happened to Ambrose.
