Tony Landry and Ursula May’s affair

Tony Landry and Ursula May’s affair is a concealed family scandal that becomes important to the investigation into Lula Landry’s death. Tony’s need to hide his relationship with Cyprian May’s wife helps explain why he supplied a misleading account of his whereabouts—and why that account temporarily supported John Bristow’s alibi.

The Affair and Its Secrecy

The affair is disclosed during Cormoran Strike’s confrontation with John Bristow. Strike tells him that he has informed Alison Cresswell both of the affair and of the impending murder arrest, and says this prompted Alison to look for a new boyfriend and a new job. In Strike’s reconstruction, Bristow had kept Alison close because he regarded her as a safeguard and as a way to learn what Tony was thinking.

Tony’s Account and the Alibi

Strike explains that Tony needed to appear to have been somewhere other than a hotel with Cyprian May’s wife. He therefore claimed to have doubled back to London to visit his sick sister. The claim placed him in the same family setting where both John and Lula were supposed to be present, making the affair relevant to the case not as a separate romance but as a source of concealment and conflicting accounts.

The Shared Lie and Its Consequences

According to Strike, Lula could not contradict Tony because she was dead. Tony nevertheless claimed to have seen John through the study door without speaking to him, while John backed up that version. Strike interprets both men as concealing their own conduct while fearing what the other might know. Tony, he suggests, may have put off confronting John until after their mother’s death, while asking Alison to keep watch on him. The affair thus sits inside a wider chain of family silences: it gives Tony a reason to disguise his movements, and his story helps preserve an alibi that Strike ultimately challenges.
