A Private Rendezvous Planned

A Private Rendezvous Planned
A message in advance
Miss Russell receives word that Charles Kent is coming to Fernly Park. She arranges to meet him away from the house, protecting her position and reputation.
A second secret
Ursula Bourne also has a reason to seek the summerhouse: she must meet her husband, Ralph Paton. The same secluded place will hold two unrelated encounters.
Kent Arrives

Kent Arrives
The stranger at the gates
Dr. James Sheppard meets a rough-voiced stranger asking the way to Fernly Park. The man is Charles Kent, though Sheppard cannot initially place the familiar quality of his voice.
A drug clue
Kent carries the goose quill used for sniffing drugs. Poirot later connects it to the summerhouse and to the visitor’s meeting with Miss Russell.
A Mother’s Secret Meeting

A Mother’s Secret Meeting
A hidden relationship
Miss Russell slips out to meet Kent in the summerhouse and gives him money. She does not reveal to him that she is his mother.
A departure before the murder
Kent leaves toward the lodge path, well before the murder is believed to have occurred. His presence looks incriminating until his alibi and Miss Russell’s explanation clarify the meeting.
The Patons Meet

The Patons Meet
An argument over secrecy
Ursula Bourne meets Ralph Paton in the summerhouse. Their secret marriage and his engagement to Flora have made their relationship bitter and precarious.
A separation under suspicion
Ursula leaves first, while Ralph remains behind. Their timing supplies Ralph with an alibi against the earliest murder window, but his later disappearance obscures the protection it might offer.
The Clues Converge

The Clues Converge
Two meetings, two motives
Poirot separates Kent’s meeting with Miss Russell from Ursula’s meeting with Ralph. The shared location had made unrelated secrets appear like one conspiracy.
A false trail resolved
The handkerchief fragment and goose quill explain visits to the summerhouse without proving anyone there killed Ackroyd. The murder’s decisive clues lie elsewhere.
