At the mention of her name a veritable fountain of venom had bubbled up, and Tarling had sensed the abysmal depths of this man's hate and something of his boundless love for the dead man.
He turned impatiently on the couch and reached out his hand for his tea, when there came a soft tap at the door and Ling Chu slipped into the room.
"The Bright Man is here," he said, and in these words announced Whiteside, who brought into the room something of his alert, fresh personality which had earned him the pseudonym which Ling Chu had affixed.
"Well, Mr.Tarling," said the Inspector, taking out a little notebook, "I'm afraid I haven't done very much in the way of discovering the movements of Miss Rider, but so far as I can find out by inquiries made at Charing Cross booking office, several young ladies unattended have left for the Continent in the past few days." "You cannot identify any of these with Miss Rider ?" asked Tarling in a tone of disappointment.
The detective shook his head.

Despite his apparent unsuccess, he had evidently made some discovery which pleased him, for there was nothing gloomy in his admission of failure.
"You have found out something, though ?" suggested Tarling quickly, and Whiteside nodded.
"Yes," he said, "by the greatest of luck I've got hold of a very curious story.

I was chatting with some of the ticket collectors and trying to discover a man who might have seen the girl--I have a photograph of her taken in a group of Stores employees, and this I have had enlarged, as it may be very useful." Tarling nodded.
"Whilst I was talking with the man on the gate," Whiteside proceeded, "a travelling ticket inspector came up and he brought rather an extraordinary story from Ashford.

On the night of the murder there was an accident to the Continental Express." "I remember seeing something about it," said Tarling, "but my mind has been occupied by this other matter.

What happened ?" "A luggage truck which was standing on the platform fell between two of the carriages and derailed one of them," explained Whiteside.
