"You may read that," she said. "It is part of a report which I have
had in my pos session since Wednesday morning."

Laverick drew the sheet towards him and read, in thin, angular
characters, very distinct and plain:

Some ten minutes after the assault, a policeman passed down
the street but did not glance toward the passage. The next
person to appear was a gentleman who left some offices on the
same side as the passage, and walked down evidently on his
homeward way. He glanced up the passage and saw the body
lying there. He disappeared for a moment and struck a match.
A minute afterwards he emerged from the passage, looked up and
down the street, and finding it empty returned to the office
from which he had issued, let himself in with his latchkey,
and closed the door behind him. He was there for about ten
minutes. When he reappeared, he walked quickly down the street
and for obvious reasons I was unable to follow him.

The address of the offices which he left and re-entered was
Messrs. Laverick & Morrison, Stockbrokers.

"That interests you, Mr. Laverick?" she asked softly.

He handed it back to her.

"It interests me very much," he answered. "Who was this unseen
person who wrote from the clouds?"

"I may not tell you all my secrets, Mr. Laverick," she declared.
