The Three Taps · Chapter

XXIII: Leyland’s Account of It All explained

Leyland presents his theory of the murder, arguing that Brinkman killed Mottram for a combination of motives: the thousand pounds and anti-clerical sentiment.

What happens

Leyland presents his theory of the murder, arguing that Brinkman killed Mottram for a combination of motives: the thousand pounds and anti-clerical sentiment. He explains that the locked door and turned-off gas tap led him to deduce that the gas came from an independent source, possibly from Brinkman's room above. Leyland describes Brinkman's plan to fake suicide, his failed attempt to turn off the gas first, and his subsequent flight. However, Bredon points out a fatal flaw: the gas tap showed marks of being turned on but not off, contradicting Leyland's theory. The chapter ends with the Bishop of Pullford arriving, claiming to have evidence that Mottram's death was suicide.
