"Tangiers," interposed Kind, taking the cigarette, "see,--this cigarette is marked 'Tangerian.' I have never seen one like that in England. It might have come from France, or from Algiers or Tangiers, but one thing we can be certain of, that the murderer came from foreign parts only a short time ago. A man doesn't keep cigarettes for months, unless he has a large quantity. The murderer may have had a quantity, but the chances are that he hadn't. In fact," Kind leaned back with the air of a man, who has made up his mind, "I believe that the man came from a ship and was a sailor, else why should he have displayed such activity in climbing up to a window."
"It's all theory," said Browne, shaking his head disconsolately.
"The cigarette isn't."
"No. All the same, I don't see how you are going to find this man."
"That must be your task, doctor."
"Mine?" Browne jumped up.
"Yes. Mr. Herries must stop here for the present. Later, when I have found the man, he can give himself up. You, doctor, know Miss Maud Tedder, the daughter of the deceased?"
"Yes."
"Then go and see her at Tarhaven. Ask her questions, for in Sir Simon's past life will be found the reason for his murder."
"But if it was blackmail, and I am bound to say that it looks like it,--and if the meeting was kept secret, I don't see what Miss Tedder will know."
