”"Going out," Emily says at the same time as Tristram answers, "Working on a case." They grin at each other and turn to Uncle Mycroft to see how he will referee the disagreement.”

What a wonderful test for Mycroft! And it’s lovely to see his sense of humour coming out here – well until he sees the bathroom, probably!

I think it’s wonderful how their fathers’ traits have rubbed off so much on both Emily and Tristram; but how they’re both able to talk each other round, when needed.
