Holmes plainly has to stop and think. Such things as physical comforts fade to insignificance for him when he has a puzzle in front of him. "I am very comfortable, yes," he tells Mary. He strips off one of his gloves and stoops to pick up a bit of snow. It immediately starts to melt in his hand. "However, I don't think it would be wise for either of us to spend a too much time outdoors." He rubs his hand dry on his trousers and puts his glove back on. "All the more reason for us to investigate the source of the smoke. After all, where there's smoke, there's fire." He offers his arm to Mary again, smiling. "Tell me Miss Poppins, are we inside the igloo?" Holmes itches to go examine the trees as well, but will postpone that for the moment.
