Fate and Coincidence

The story explores the role of chance in the murder, from the fog that enables the crime to the discovery of the golf ball and the book, with characters debating whether events are coincidental or deliberately planned.

The sliced golf ball leads the golfers to discover the body, and the stopped watch coincidentally matches the train time.

The discovery of the key book through a porter's wife and the timely decoding of the warning message suggest a pattern of fateful coincidences.

The fog, the train's delay at the viaduct, and the discovery of the golf ball all contribute to the chain of events that lead to the murder's unraveling.

The coincidence of Marryatt seeing the stick and hearing the speaking tube at the same time as Reeves' message leads to his dramatic flight, highlighting the role of chance in the plot.
