“Ah, if I could give it a name it might go a long way towards solving the case. On the whole, it was probably some creature of the weasel and stoat tribe⁠—and yet it is larger than any of these that I have seen.”

We know that a man stood in the road looking at the quarrel between the Barclays⁠—the blinds were up and the room lighted. We know, also, that he ran across the lawn, entered the room, accompanied by a strange animal, and that he either struck the Colonel or, as is equally possible, that the Colonel fell down from sheer fright at the sight of him, and cut his head on the corner of the fender. Finally, we have the curious fact that the intruder carried away the key with him when he left.”
