"No, sir. After a while the patrolmen arrived and we threw a cordon around the house, but no one was seen."
Gordon shrugged his shoulders; a few cursory questions had satisfied him that the captives were harmless addicts and he had them released.
"You are sure no one else came out?"
"Yes, sir—no, wait a moment. A wretched old blind beggar did come out, all rags and dirt and with a ragged girl leading him. We stopped him but didn't hold him—a wretch like that couldn't be harmful."
"No?" Gordon jerked out. "Which way did he go?"
"The girl led him down the street to the next block and then an automobile stopped and they got in and drove off, sir."
Gordon glared at him.
"The stupidity of the London detective has rightfully become an international jest," he said acidly. "No doubt it never occurred to you as being strange that a Limehouse beggar should ride about in his own automobile."
Then impatiently waving aside the man, who sought to speak further, he turned to me and I saw the lines of weariness beneath his eyes.
"Mr. Costigan, if you will come to my apartment we may be able to clear up some few things."
