Theodosia Throckmorton is in a fix. Allowed to attend a reception given by one of the directors of her parents' museum, she unexpectedly stumbles across Mr. Tetley of the British Museum in most unusual circumstances! Since Theodosia last saw him in a showdown in an ancient Egyptian tomb, his reappearance could mean only one thing: the Serpents of Chaos are back. Once again Theodosia will have to take on secret societies, evil curses, and dark magic too sinister to imagine. Blocked at every turn, Theodosia will have to rely on her own skill and cunning--along with a little help from the most unexpected places--to avoid an evil conspiracy that strikes at the very heart of Britain.
