Lettice Breech is itching to go on another adventure.
But her beloved Pa is sick, and their home is in danger. Letty needs money. She needs treasure.
So, when a mysterious socialite appears in London, promising more treasure than she can imagine, Letty finds herself embroiled in a thrilling new mystery right in her home city. Baffling poems, puzzling clues in dictionaries, and curious notes from a mysterious group known only as The Alphabetters lead Letty on a whirlwind adventure through the streets of London. And then there is - nearly - a murder . . .
Can Letty use her deductive skills to unravel the mystery of the word thieves?
