Cumberholmes based fic - what was in the package, and why it was important

This won't make sense to non @cumberholmes people, but when working out what was in the package yesterday, why the things were important and why he gave them to Irene and John, I came up with little backstories for the items - then Sherlock, being Sherlock, was never going to tell them.

WARNING - continues the Sentimentality of yesterday in general. Sweetness turned up to 11 and all that jazz.

I quickly wrote them down here, in case you're interested.
