Letter: Elementary mistake

Sir: Centenary of the death of Sherlock Holmes? 12 October 1993? Poppycock] As the whole world knows, Sherlock Holmes met his supposed death, at the hands of his arch-enemy Professor Moriarty, on 4 May 1891. So Royal Mail has missed the centenary by two years, five months and eight days. That's rather longer than the expected delay to the opening of the Channel Tunnel, whose commemorative philatelic issue this Sherlock Holmes series has hastily replaced.

Yours faithfully,
