The nattily-named “Spycatcher of Knightsbridge” offers this pen with a UV light for detecting invisible ink and a built-in message shredder available for under $10. Sounds like there may be a shortage of spies to catch in Knightsbridge, so Spycatcher is helping them out a bit in procuring equipment.
