Chapter 15, Strange Behavior of Frederica and Chapter 16, Interview with Mr. Whitfield Summary

In Chapter 15, Colonel Weston, the Chief Constable, visits Poirot. He's grateful for Poirot's help, hoping to keep the case away from Scotland Yard. He despairs of getting evidence, and Poirot says that the gun has likely been thrown into the ocean. Westion says Vyse is cautious, and if he's the killer, it will be hard to prove. If the killer is Freddie, she'll likely get impatient and try again. The inquest is the next day, but details about Nick will be kept from the public. Maggie's parents are coming in from Yorkshire. Before he leaves, Weston shows Poirot a paper the police found on the grounds, a torn scrap asking for money. Poirot gets permission to hold onto the paper.
