Who should be hobnobbing with the great and the good at a Buckingham Palace garden party but little Miss Emily Seeton, retired teacher and artistic sleuth. It seems there may be a traitor amongst HM’s faithful retainers.
But while Miss Seeton is viewing shrunken heads and other royal treasures with Sir Wormelow Tump, a plan is being hatched by a titled crook to steal valuables of a different kind – a fabulous set of Lalique jewellery.

Serene amidst every kind of skulduggery, this eccentric English spinster steps in where Scotland Yard stumbles, armed with nothing more than her sketchpad and umbrella!
