Page "Strong Poison" Paragraph 7

Wimsey visits Harriet in prison, declares his conviction of her innocence, and promises to catch the real murderer.

In the course of the interview he also openly admits his intention of marrying her, an offer which she politely but firmly declines.

Working against time before the new trial, Wimsey first explores the possibility that Boyes took his own life.

Wimsey's friend, Detective Inspector Charles Parker, conclusively disproves this notion, but Wimsey has planted a spy, Miss Joan Murchison, in Urquhart ’ s office and discovers the real culprit is Urquhart.
