When I decided to mark Advent by celebrating serendipity I had no idea that Serendipity would appear at my feet on a morning dog walk. Just where a dog shadow is projected on the pavement you can see a metal insert. This is one of many Sherlock Holmes quotes that run along this street. For a few years Conan Doyle lived on this street and ran his G.P practice here. These quotations are a gentle homage to the author and his most famous character.

I have walked this way hundreds of times and never before have I seen this particular quotation.

It is serendipitously apt because this blog is almost entirely created upon the observation of trifles. And yet I have failed to observe this quote until today. Doubly serendipitously I used to catch my bus home from University College in London opposite 221 b Baker Street the literary address of Sherlock Holmes.

Two linked but insignificant trifles.
