"I picked up one or two hints from the county police as to the geography as well as the 'notables' of the neighborhood; and the plan which you put into execution to-night, I had adopted last night!"

"What! You visited Friar's Park?"

"I did. But I did not enter through the French window. It never occurred to me that it would be unfastened! I had come provided with a neat set of burglars' tools (and a warrant for use if necessary) and I broke into the kitchen! I found, as you afterwards found, that the place had obviously been deserted for a long time. I was badly puzzled. But my search was more detailed than yours. I climbed up to the top of the tower!"

"To the top of the tower!"

"Yes. I'll tell you what I found there in a minute. But, briefly, beyond learning that the story of the invalid Lady Coverly was a myth, I discovered nothing likely to help the inquiry. I seriously debated the idea of putting Dr. Damar Greefe under arrest; but finally I determined to watch him for a time without showing my hand. I had the good fortune to meet him this morning here at the Abbey Inn! Also, I saw your mysterious lady visitor! Lastly, I got into conversation with the man, Hawkins, who was accompanied by your friend, the mute!

"Leaving this dangerous pair, I made a rush for the Bell House, thinking I saw my opportunity to examine it unmolested. I was too late, though. One of my assistants warned me of the Eurasian's return just as I was about to enter.

"I watched the house all day. But it was not until some time after dusk that the Eurasian came out. He went to Friar's Park—and I followed him!"

"What! You were there to-night!"

"I was! I dogged Dr. Damar Greefe, determined to learn the nature of the business which brought him to Friar's Park at such an hour. I may add that it was only by the merest accident or good luck that I fathomed it after all. I had no idea into what part of the building he had gone, but, knowing that he was somewhere inside, I watched from the shrubbery. In fact, I was still in the grounds when you arrived!"

"Then it was you I saw on the tower!"
