Mystrade, on a boat.
Greg stood to stretch for the picnic basket and then yelped, grabbing for the sides of the boat as it threatened to heave him into the drink.
Mycroft reached out and plucked him like a hanging fruit, pulling him down and securing him with long arms in his lap. ”Prince of the city,” he intoned, more smugly than Greg thought was strictly necessary, “helpless babe in the woods.”
