A further selection of anecdotes from the world's first consulting detective. Our walk starts at the Royal Exchange, just a one minute walk from Bank Underground and finishes at Aldgate Station approximately 90 minutes later. No previous knowledge of Sherlock Holmes is necessary but if you have read any Sherlockian stories, so much the better.

Autumn in the city can be glorious but unpredictable, so please dress for the weather on the day and appropriate footwear is recommended. Check you journey options at www.tfl.gov.uk before you set out.

I look forward to your company as we solve those mysteries that fascinate Mr Sherlock Holmes...
