"Suppose we say the mummy?"

Weymouth laughed uneasily.

"Well, sir, something that vanished from a locked room without opening the door or the window killed Strozza."

"And something which, having killed Strozza, next killed the Chinaman, apparently without troubling to open the door behind which he lay concealed," Smith continued. "For once in a way, Inspector, Dr. Fu-Manchu has employed an ally which even his giant will was incapable entirely to subjugate. What blind force—what terrific agent of death—had he confined in that sarcophagus!"

"You think this is the work of Fu-Manchu?" I said. "If you are correct, his power indeed is more than human."

Something in my voice, I suppose, brought Smith right about. He surveyed me curiously.

"Can you doubt it? The presence of a concealed Chinaman surely is sufficient. Kwee, I feel assured, was one of the murder group, though probably he had only recently entered that mysterious service. He is unarmed, or I should feel disposed to think that his part was to assassinate Sir Lionel whilst, unsuspecting the presence of a hidden enemy, he was at work here. Strozza's opening the sarcophagus clearly spoiled the scheme."

"And led to the death—"

"Of a servant of Fu-Manchu. Yes. I am at a loss to account for that."

"Do you think that the sarcophagus entered into the scheme, Smith?"
