Lord Peter is increasingly committed to exonerating Harriet Vane and begins to grow suspicious that Norman Urquhart, cousin of Peter Boyes and nephew/executor of senile but wealthy Mrs. Wrayburn, has substituted a false will for the genuine one making himself the sole heir. Wimsey recruits Miss Murchison. Urquhart's secretary, to his cause and recruits a reformed Cockney thief to teach her how to pick the lock and find the real will.
