When the Al-Ikhwan Diamond, the largest in the known world, goes missing from the Tower of London, Detective Sergeant Carter of the Yard, knows of only one person who can assist him in discovering those responsible; but Thrillington has her own problems when she discovers the very same jewel inside the mystery that is Thrillington Hall.
