Dear Sherlock,

It's Halloween! I'm writing this straight from your grave tonight, sat on the damp, cold ground trying to figure out exactly what I'm doing writing it here rather than at home where it's warm and I have a real desk to lean on rather than my knee. Maybe it's because it feels quite magical here. There are candles in big glass jars and pumpkins with lights in and red lanterns hanging from the trees. It's really pretty, but I'm the only one here to notice it, because I don't think many people like to be in a dark, cold graveyard on Halloween night. Just me, then, who gets to see how extraodinary it is. Hats off to the groundskeeper, even though I still think he's stealing these letters and the papers I leave. Bet he doesn't have to buy his own now, he can just wait a week for these ones.

Mrs Hudson's been handing out all sorts of sweets and chocolate to the trick-or-treaters. I carved a pumpkin for the occasion - no trouble with the knife this time. Although it was a messy business to start with and a messy result at the end. I put the deerstalker on it, to keep its head nice and snug. You're probably hoping that it'll burn up, aren't you? Well let me tell you that it's quite safe and out of danger from any sort of flame. It's memories, Sherlock, so don't complain. Sentiment.

We dressed Lestrade up as a zombie. He looks fantastic! I'm leaving a picture so that you can see for yourself. He's a great sport. I'm so glad I got to meet him. Again, that's thanks to you.

Love,

Your John.
