arylebone Road," said the lady.

T. X. sat up.

"Yes?" he said quickly. "What about your young lady?"

"She works as far as I can understand," said the loquacious landlady,
"with a certain Mr. Kara in the typewriting line. She came to me four
months ago."

"Never mind when she came to you," said T. X. impatiently. "Have you a
message from the lady?"

"Well, it's like this, sir," said Mrs. Cassley, leaning forward
confidentially and speaking in the hollow tone which she had decided
should accompany any revelation to a police officer, "this young lady
said to me, 'If I don't come any night by 8 o'clock you must go to T. X.
and tell him--'!"

She paused dramatically.

"Yes, yes," said T. X. quickly, "for heaven's sake go on, woman."

"'Tell him,'" said Mrs. Cassley, "'that Belinda Mary--'"

He sprang to his feet.

"Belinda Mary!" he breathed, "Belinda Mary!" In a flash he saw it all.
This girl with a knowledge of modern Greek, who was working in Kara's

It brought a strange glow to his heart that Belinda Mary should have

"Only as a policeman, of course," said the still, small voice of his
official self. "Perhaps!" said the human T. X., defiantly.

He got on the telephone to Mansus and gave a few instructions.

"You stay here," he ordered the astounded Mrs. Cassley; "I am going to
make a few investigations."

Kara was at home, but was in bed. T. X. remembered that this
extraordinary man invariably went to bed early and that it was his
practice to receive visitors in this guarded room of his. He was
admitted almost at once and found Kara in his silk dressing-gown lying
on the bed smoking. The heat of the room was unbearable even on that
bleak February night.

"This is a pleasant surprise," said Kara, sitting up; "I hope you don't
mind my dishabille."

T. X. came straight to the point.

"Where is Miss Holland!" he asked.

"Miss Holland?" Kara's eyebrows advertised his astonishment. "What an
extraordinary question to ask me, my dear man! At her home, or at the
theatre or in a cinema palace--I don't know how these people employ
their evenings."

"She is not at home," said T. X., "and I have reason to believe that she
has n
