In 2006, an Agatha Christie fan took part at an auction of the author’s property. The fan purchased a trunk for 100 pounds. In the trunk was a sealed strongbox, still locked. 4 years passed until the new owner of… the box could open it (with a crowbar from a contractor doing renovations on the fan’s house), Upon opening the box, she discovered a diamond buckle brooch, gold coins and a three stone diamond ring! This is the buckle brooch that was re-sold at a Bonhams auction.
