Set out the timeline of the murder at Kew Gardens | The Kew Gardens Drama SH: Crimes and Punishments Guide
Last update: 11 May 2016
When in Kew Gardens again, head to the Palm house. Examine the body in the vestibule: Neck, Martyn Hamish's letter (Martyn Hamish's regret) and his feet (the left one).
Deduction
Connect "Hamish's confession" with "Club foot". You will obtain "Hamish acted alone?" and a task: "Talk to Lestrade".
It's time to check if Miss White is trustworthy. Head to the laboratory and open a cupboard to the right of the fireplace. Examine the Phonograph cylinders inside and take Cylinder 320.
Approach the Phonograph on the desk and select: Use cylinder. Turn the handle and listen to the recording. It will confirm Margaret's words.
Return to the Palm house and talk to Lestrade.
