intruder."

"But you did not see him?"

"Only his shadow"

"What!"

"You can obtain the evidence of all my household that someone had
actually entered," declared Colonel Menendez, eagerly. "Of this, at
least, I can give you the certain facts. Whoever it was had obtained
access through a kitchen window, had forced two locks, and was coming
stealthily along the hallway when the sound of his footsteps attracted
my attention."

"What did you do?"

"I came out on to the landing and looked down the stairs. But even the
slight sound which I made had been sufficient to alarm the midnight
visitor, for I had never a glimpse of him. Only, as he went swiftly
back in the direction from which he had come, the moonlight shining in
through a window in the hall cast his shadow on the carpet."

"Strange," murmured Harley. "Very strange, indeed. The shadow told you
nothing?"

"Nothing at all."

Colonel Menendez hesitated momentarily, and glanced swiftly across at
Harley.
