In the tantalizing finale to the Truly Devious trilogy, New York Times bestselling author Maureen Johnson expertly tangles her dual narrative threads and ignites an explosive end for all who’ve walked through Ellingham Academy. Now in paperback.

Ellingham Academy must be cursed. Three people are now dead. One, a victim of either a prank gone wrong or a murder. Another, dead by misadventure. And now, an accident in Burlington has claimed another life. All at the exact moment of Stevie’s greatest triumph . . .

She knows who Truly Devious is. She’s solved it. The greatest case of the century.

At least, she thinks she has. With this latest tragedy, it’s hard to concentrate on the past. Not only has someone died in town, but David has disappeared of his own free will and is up to something. Stevie is sure that somehow—somehow—all these things connect.

The three deaths in the present. The deaths in the past. The missing Alice Ellingham and the missing David Eastman. Somewhere in this place of riddles and puzzles there must be answers.

Then another accident occurs as a massive storm heads toward Vermont. Ellingham Academy is evacuated.

Obviously, it’s time for Stevie to do something stupid. It’s time to stay on the mountain and face the storm—and a murderer.
