What happens
Inspector Tanner interviews Lady Ponson and Enid, then spends Sunday examining Sir William's papers with Sergeant Longwell. He discovers cheques made out to 'self' marked with an 'X', totaling £4,600 over four years. He consults lawyer Arbuthnot about family finances and learns of Austin's engagement to Lois Drew, which Sir William opposed. Tanner also interviews Parkes and Innes, learning Sir William became depressed after receiving a letter a week before his death. He decides to test Austin's alibi, trace the fifth set of footsteps, and continue routine investigation.
Themes in this chapter
Secrecy and Blackmail
The mysterious 'X' cheques suggest a secret payment or blackmail, as Sir William wrote them to 'self' with only a cryptic mark.
Family Loyalty and Conflict
Sir William's disappointment in Austin and preference for Cosgrove, along with the engagement dispute, highlight family tensions.
Wealth and Motive
The large inheritance (£500,000) and the financial positions of Austin, Cosgrove, and Enid provide potential motives for murder.

Sir William's nephew; described as a waster, inherits £75,000, and is financially pinched.

Key passages
“Both had noticed Sir William had not been quite up to his usual form for a few days before their departure for London, but both had put it down to some trifling physical indisposition, and neither could throw light on any possible cause of worry to him.”
Lady Ponson and Enid observed that Sir William seemed off-color before they left for London, but they attributed it to a minor illness and couldn't identify any source of anxiety.
Tanner's interview with the ladies reveals no obvious motive or enemy.
“What had specially intrigued the Inspector’s imagination was the fact that below the word “self” was in each case one letter only—a capital X.”
The Inspector was particularly puzzled because each cheque made out to 'self' had only a capital 'X' where the purpose was usually written.
The 'X' cheques are a key clue suggesting a hidden secret.
“He was extremely annoyed at the idea, because, though he admitted that so far as he knew Miss Drew was personally all that could be desired, her social standing was not good.”
Sir William was very upset about Austin's engagement to Lois Drew because he felt her social position was beneath the family's standards, even though he had no personal objection to her.
This reveals a motive for conflict between Sir William and Austin.
