In 1993 the Royal Mail in Great Britain issued a set of five se-tenant stamps to honor the legendary fictional detective Sherlock Holmes. The stamps depicted iconic scenes from The Reigate Squire, The Hound of the Baskervilles, The Six Napoleons, The Greek Interpreter, and The Final Problem.
Hidden within the design of each stamp is a single letter; the five letters (D, E, L, O, and Y) can be anagrammed to form a relevant word other than "yodel." The question is whether you can locate the five letters. You will need good eyes, perhaps a magnifying glass, and a supersized image (available here - click twice). Those who are curious, but too impatient to do the searching, can avoid the fun and skip to the solution.
