“Nothing has happened, sir,” he replied. “The telephone is ringing in the study now, though.”

“I will answer it myself,” the Professor declared, bustling off.

He hurried across the bare landing and into an apartment which seemed to be half museum, half library. There were skeletons leaning in unexpected corners, strange charts upon the walls, a wilderness of books and pamphlets in all manner of unexpected places, mingled with quaintly-carved curios, gods from West African temples, implements of savage warfare, butterfly nets. It was a room which Lord Ashleigh was never able to enter without a shudder.

The Professor took up the receiver from the telephone. His “Hello” was mild and enquiring. He had no doubt that the call was from some admiring disciple. The change in his face as he listened, however, was amazing. His lips began to twitch. An expression of horrified dismay overspread his features. His first reply was almost incoherent. He held the receiver away from him and turned towards his brother.

“George,” he gasped, “the greatest tragedy in the world has happened! My ape is stolen!”

His brother looked at him blankly.

“Your ape is stolen?” he repeated.

“The skeleton of my anthropoid ape,” the Professor continued, his voice growing alike in sadness and firmness. “It is the curator of the museum who is speaking. They have just opened the box. It has lain for two days in an anteroom. It is empty!”

Lord Ashleigh muttered something a little vague. The theft of a skeleton scarcely appeared to his unscientific mind to be a realisable thing. The Professor turned back to the telephone.

“Mr. Francis,” he said, “I cannot talk to you. I can say nothing. I shall come to you at once. I am on the point of starting. Your news has overwhelmed me.”
