Disclaimer: I only own Hathaway's friend, unfortunately.
Lewis and Hathaway are sat discussing the case and possible leads in Hathaway's lounge, drinking beer. The detritus from their Chinese littered the coffee table but neither of them made any move to get rid of it. They just relaxed back on the sofa until,
"D'you mind if I use your bathroom?"
"No, go ahead"
Lewis got up as Hathaway sat there, fondling his beer bottle, looking contemplative. It was a long, complex case but his thoughts were currently far from any criminal activity, if the gentle smile on his face was anything to go by. This was an expression very few ever saw.
A few minutes later, Lewis came back down the stairs looking with amusement at an object he held in his hand.
"Y'know, I haven't seen one of these since the kids were young. Do they even make them anymore; I mean this colour? I thought they were all different colours these days."
"That's Bubbles sir, been my bath friend for years, she's been with me everywhere."
Lewis just stared at the rubber duck with amusement. Trust Hathaway to have just one more surprise tucked up his sleeve (or in his bath!).
