The first thing Dr. Silence did was to lock up Smoke in the study with a saucer of milk before the fire, and then make a search of the house with Flame. The dog ran cheerfully behind him all the way while he tried the doors of the other rooms to make sure they were locked. He nosed about into corners and made little excursions on his own account. His manner was expectant. He knew there must be something unusual about the proceeding, because it was contrary to the habits of his whole life not to be asleep at this hour on the mat in front of the fire. He kept looking up into his master’s face, as door after door was tried, with an expression of intelligent sympathy, but at the same time a certain air of disapproval. Yet everything his master did was good in his eyes, and he betrayed as little impatience as possible with all this unnecessary journeying to and fro. If the doctor was pleased to play this sort of game at such an hour of the night, it was surely not for him to object. So he played it, too; and was very busy and earnest about it into the bargain.
