At the door of the house we were met by a tall, white-faced, flaxen-haired man, with a notebook in his hand, who rushed forward and wrung my companion’s hand with effusion. “It is indeed kind of you to come,” he said, “I have had everything left untouched.”

“Except that!” my friend answered, pointing at the pathway. “If a herd of buffaloes had passed along there could not be a greater mess. No doubt, however, you had drawn your own conclusions, Gregson, before you permitted this.”

“I have had so much to do inside the house,” the detective said evasively. “My colleague, Mr. Lestrade, is here. I had relied upon him to look after this.”

Holmes glanced at me and raised his eyebrows sardonically. “With two such men as yourself and Lestrade upon the ground, there will not be much for a third party to find out,” he said.
