Lexman, and I had no idea that I should meet a policeman." "My dear Mr.Kara," said T.X., rising and lighting a cigarette, "you will go through life enduring that unhappy experience." "What do you mean ?" "Just what I say.

You will always be expecting to meet one person, and meeting another, and unless you are very fortunate indeed, that other will always be a policeman." His eyes twinkled for he had recovered from the gust of anger which had swept through him.

"What we want is the weapon which the Greek had when he threatened Mr.Lexman." "There, I'm afraid I cannot help you." Kara walked to the door and T.X.

followed.
"I think I will see Mrs.Lexman." "I think not," said T.X.
The other turned with a sneer.
"Have you arrested her, too ?" he asked.
"Pull yourself together!" said T.X.coarsely.
