“The negro or Hamitic heel!” Reggie murmured. “Do you remember, Lomas old thing?”

“Good Gad!” Lomas dropped his eyeglass. “But what the devil can we do?”

“Watch and pray,” said Reggie. “Your fellows watch Sherif and Blenkinhorn and Osbert and you pray. Do you pray much, Lomas?”

They went in fact to lunch. They were not long back when a detective speaking over the telephone reported that a man of mulatto appearance had called on Colonel Osbert. Reggie sprang up. “Come on, Lomas. We’ll have them in the act and bluff the whole thing out of them.”

“What act?”

“Collusion. This Egyptian-Syrian-negroid-Young Turk and the respectable executor. Come on, man.”

In five minutes they were mounting to Colonel Osbert’s flat. His servant could not say whether Colonel Osbert was at home. Lomas produced his card. “Colonel Osbert will see me,” he announced, and fixed the man with a glassy stare.

“Well, sir, I beg pardon, sir. There’s a gentleman with him.”

“At once,” said Lomas and walked into the hall.

The man still hesitated. From one of the rooms could be heard voices in some excitement. Lomas and Reggie made for that door. But as they approached there was a cry, a horrible shrill cry, and the sound of a scuffle. Reggie sprang forward. Some one rushed out of the room and Reggie, the smaller man, went down before him. Lomas clutched at him and was kicked in the stomach. The fellow was off. Reggie picked himself out of the hatstand and ran after him. Lomas, in a heap, gasping and hiccoughing, fumbled in his pocket. “B-b-blow,” he stammered to the stupefied servant, and held out a whistle. “Like hell. Blow!”
