The Truly Devious case—an unsolved kidnapping and triple murder that rocked Ellingham Academy in 1936—has consumed Stevie for years. It’s the very reason she came to the Academy. But after she arrives, more students turn up dead. Teen detective Stevie is on the case until she solves every mysterious death—from the past and the present.

Praise for Truly Devious:

“Parallel mysteries unfold with cleverly written dialogue, pate-turning brilliance, and a young sleuth as captivating as Hercule Poirot.”

“The Agatha Christie-like ecosystem pairs with lacerating contemporary wit. A multilayered, modern detective story.”

Praise for The Vanishing Stair:

“Take it from the world’s most impatient reader: If the Truly Devious series is basically one long mystery book, The Vanishing Stair is middle part so enjoyable you won’t even want to skip to the end.”

Praise for The Hand on the Wall:

“A richly satisfying, Poirot-like ending for Johnson's inspired and inspiring teen sleuth.”
