Licking Christie

Via B.V. Lawson’s In Reference to Murder comes this news:

Crime writer Agatha Christie’s murder mystery novels are getting a new outing—as stamps. The Royal Mail in the UK has issued six stamps to mark the centenary of the year Christie wrote her first detective novel, The Mysterious Affair at Styles, which introduced Belgian detective Hercule Poirot to the world. But these aren’t just ordinary stamps—they contain hidden clues and references, printed in special inks and microtext, to murders and key scenes in Christie’s most famous novels. Amateur sleuths will be able to use UV light, body heat and a magnifying glass to uncover hidden elements and key scenes in the stamps.

Welcome to the 21st century, Dame Agatha!
