A classic mystery featuring legendary detective, Hercule Poirot.

A ruthless international cartel seeks world domination…Framed in the doorway of Poirot’s bedroom stood an uninvited guest, coated from head to foot in dust. The man’s gaunt face stared for a moment, then he swayed and fell. Who was he? Was he suffering from shock or just exhaustion? Above all, what was the significance of the figure 4, scribbled over and over again on a sheet of paper?

The intense interest aroused in the public by what was known at the time as “The Styles Case” has now somewhat subsided. Nevertheless, in view of the world-wide notoriety which attended it, I have been asked, both by my friend Poirot and the family themselves, to write an account of the whole story. This, we trust, will effectually silence the sensational rumours which still persist.I will therefore briefly set down the circumstances which led to my being connected with the affair.

It was 2 p.m. on the afternoon of May 7, 1915. The Lusitania had been struck by two torpedoes in succession and was sinking rapidly, while the boats were being launched with all possible speed. The women and children were being lined up awaiting their turn. Some still clung desperately to husbands and fathers; others clutched their children closely to their breasts. One girl stood alone, slightly apart from the rest. She was quite young, not more than eighteen. She did not seem afraid, and her grave, steadfast eyes looked straight ahead. “I beg your pardon.” A man’s voice beside her made her start and turn. She had noticed the speaker more than once amongst the first-class passengers. There had been a hint of mystery about him which had appealed to her imagination. He spoke to no one. If anyone spoke to him he was quick to rebuff the overture. Also he had a nervous way of looking over his shoulder with a swift, suspicious glance. She noticed now that he was greatly agitated. There were beads of perspiration on his brow. He was evidently in a state of overmastering fear. And yet he did not strike her as the kind of man who would be afraid to meet death! “Yes?” Her grave eyes met his inquiringly. He stood looking at her with a kind of desperate irresolution. “It must be!” he muttered to himself. “Yes—it is the only way.” Then aloud he said abruptly: “You are an American?” “Yes.” “A patriotic one?” The girl flushed.
