"Oh good," Watson said, doing as asked and peering with a little squint at the houses in question. "Sneaky time." He said it with the mild sort of sarcasm that he was good at. Nothing too sharp, not for Wilson. Just an unassuming sort of British, he was.
He clearly did not think too highly of Sneaky Time. Probably because he was bad at it.
But Sherlock had what Watson liked to consider his game face on, and so he didn't say anymore -- just parked, exited the car, and waited to do his following trick. He wondered, vaguely, if he should have brought his gun.
