The Disappearing Eye by Fergus Hume — Read

So Miss Destiny was the criminal after all, and her confession alone revealed what had taken place in Anne Caldershaw's back room, shortly before I had arrived in my motor car to search for adventure. Inspector Dredge came to The Lodge that same evening to relate all that had taken place, and to inform us how he had come to Burwain. The little woman's body was found broken in pieces on the outskirts of Tarhaven, and small wonder, considering the terrible height from which she had fallen. We did not hear until the next day what Weston thought, as his airship proved to be unmanageable, and drifted over toward the island of Grain, where he managed to descend. There he remained for the night, and came back by train to Burwain in the afternoon of the ensuing day. But neither Gertrude nor I troubled about Weston's failure or absence. We were far too much taken up with the story told by Inspector Dredge.

"As you were so much connected with the matter, Mr. Vance," said the stern-faced man, when he appeared at four o'clock in the drawing-room of The Lodge, "it is only fair that you should know the truth."
