"Somebody in one of the front rooms," said the Inspector. "I'll slip along and open the front door, bring in the man from outside, and then we'll burst into the room and take our chance of capturing them."

He did as he proposed, and when the constable had joined us we moved towards the room on the left.

Again the mutterings came from the inside, and the Inspector turned the handle of the door. It was locked, however. "Let me burst it in," I whispered.

He nodded, and I accordingly put my shoulder against it, and bringing my strength to bear sent it flying in.

Then we rushed into the room, to find it, at first glance, empty. Just at that moment, however, the muttering began again, and we looked towards the darkest corner; somebody was there, lying on the ground. I rushed across and knelt down to look. It was Beckenham; his mouth gagged and his hands and feet bound. The noise we had heard was that made by him trying to call us to his assistance.

In less time than it takes to tell I had cut his bonds and helped him to sit up. Then I explained to the Inspector who he was.

"Thank God you're found!" I cried. "But what does it all mean? How long have you been like this? and where is Nikola?"

"I don't know how long I've been here," he answered, "and I don't know where Nikola is."

"But you must know something about him!" I cried. "For Heaven's sake tell me all you can! I'm in awful trouble, and your story may give me the means of saving a life that is dearer to me than my own."

"Get me something to drink first, then," he replied; "I'm nearly dying of thirst; after that I'll tell you."
