Will Thoday is an agricultural laborer whose most dominant trait is his devotion and protection of his wife Mary. Will Thoday is the one who ties Jeff Deacon up in the bell chamber, which inadvertently brings about Deacon's death. His motivation for assisting Jeff Deacon even though Deacon was a known criminal was to protect his wife's reputation and to cover up the fact that he was not legally married to Mary - her husband was still alive, even though everyone believed him to be dead and that she was a young widow when he married her. He also takes great pains to hide the truth from Mary and only unwillingly tells her after Lord Peter shows her the cipher letter and she realizes her first husband had been alive after her remarriage. He only confesses to the police after they suggest that Mary may be the guilty party rather than him - he will do anything to protect her and her reputation, especially as she has already had a brush with the law.
