221B

I took advantage of nicer weather, and my cold being almost gone, and my knee feeling a bit better to walk the 4 miles into the city centre.
On the way I passed 221B. Every time I walk or drive past this insignificant doorway it makes me think of Sherlock Holmes. I'm sure the owners are aware of the connection too since no other doors have such a prominent number on them.

In real life the pic is just dull silver numbers on a grey stone wall, so unusually for me I've got nuts with the Photoshop hues and saturation buttons to get the vivid colours.
