Britain Releases Postage Stamps Embedded With Hidden Clues to Honor Agatha Christie

160920_EYE_AgathaChristieStampsRoyalMail6 — “Poirot and Hastings investigate the crime scene,” Sutherland said, “forming the skull, as the murderer used poison. The whole stamp is then reproduced in miniature on the poison bottle.”

It’s been 100 years since Agatha Christie wrote her first detective novel, The Mysterious Affair at Styles (published in 1920), giving life to Hercule Poirot. To mark the occasion, the U.K.’s Royal Mail has released a set of innovative stamps dedicated to six of her most famous works.

Designed by London-based Studio Sutherland in collaboration with British illustrator Neil Webb, the stamps are dedicated to key scenes and principal characters from Christie’s Murder on the Orient Express, The Mysterious Affair at Styles, The Body in the Library, And Then There Were None, The Murder of Roger Ackroyd, and A Murder Is Announced.

160920_EYE_AgathaChristieStampsRoyalMail3 — “The island is the profile of the unknown killer and host,” Sutherland said. “The poem, key to the plot, is the moon’s reflection. The mysterious U.N. Owen appears at the lit window.”

Mystery lovers can use UV light, body heat, or a magnifying glass to search for clues from each book that are embedded into the stamps using microtext and heat-sensitive and UV inks.

“Trying to sum up complex plots in one frame is tricky but very rewarding,” designer Jim Sutherland said in an email, “without giving anything away, other than the clues to the murderers.”

I loved the idea that you need magnifying glass to read some of the clues—as stamp collectors use them as well as sleuths.”
