"From the Plymouth hotel, Watson," he said. "I learned the name of it from the vicar, and I wired to make certain that Dr. Leon Sterndale's account was true. It appears that he did indeed spend last night there, and that he has actually allowed some of his baggage to go on to Africa, while he returned to be present at this investigation. What do you make of that, Watson?" "He is deeply interested." "Deeply interested--yes. There is a thread here which we had not yet grasped and which might lead us through the tangle. Cheer up, Watson, for I am very sure that our material has not yet all come to hand. When it does we may soon leave our difficulties behind us." Little did I think how soon the words of Holmes would be realized, or how strange and sinister would be that new development which opened up an entirely fresh line of investigation. I was shaving at my window in the morning when I heard the rattle of hoofs and, looking up, saw a dog-cart coming at a gallop down the road. It pulled up at our door, and our friend, the vicar, sprang from it and rushed up our garden path. Holmes was already dressed, and we hastened down to meet him. Our visitor was so excited that he could hardly articulate, but at last in gasps and bursts his tragic story came out of him. "We are devil-ridden, Mr. Holmes! My poor parish is devil-ridden!" he cried. "Satan himself is loose in it! We are given over into his hands!" He danced about in his agitation, a ludicrous object if it were not for his ashy face and startled eyes. Finally he shot out his terrible news. "Mr. Mortimer Tregennis died during the night, and with exactly the same symptoms as the rest of his family." Holmes sprang to his feet, all energy in an instant. "Can you fit us both into your dog-cart?" "Yes, I can." "Then, Watson, we will postpone our breakfast. Mr. Roundhay, we are entirely at your disposal. Hurry--hurry, before things get disarranged." The lodger occupied two rooms at the vicarage, which were in an angle by themselves, the one above the other. Below was a large sitting-room; above, his bedroom. They looked out upon a croquet lawn which came up to the windows. We had arrived before the doctor or the police, so that everything was absolutely undisturbed. Let me describe exactly the scene as we saw it upon that misty March morning. It has left an impression which can never be effaced from my mind.
