Best friends and seventh graders Sophie Young and Grace Yang have made a game out of spying on their neighbors. On one of their midnight stakeouts, they witness a terrifying, bloody scene at the home of their bizarre middle-school counselor, Dr. Charlotte Agford (aka Dr. Awkward). At least, they think they do. The truth is that Dr. Agford was only making her famous pickled beets! But when Dr. Agford begins acting even weirder than usual, Sophie and Grace become convinced that she’s hiding something—and they’re determined to find out what it is. Soon the girls are breaking secret codes, being followed by a strange blue car, and tailing strangers with unibrows and Texas accents. But as their investigation heats up, Sophie and Grace start to crack under the pressure. They might solve their case, but will their friendship survive? Perfect for fans of The Mysterious Benedict Society, The Wig in the Window is a smart, funny middle-grade mystery with a REAR WINDOW twist.

Sophie Young and Grace Yang have been taking it easy ever since they solved the crime of the century...well, at least the biggest crime Luna Vista has ever seen. But things are getting exciting again now that everyone is gearing up for the 125th annual Winter Sun Festival—a town tradition that involves floats, a parade, and a “royal” court made up of local high school girls. When Festival president Jim Steptoe turns up dead on the first day of parade preparations, police blame a malfunctioning giant s’more feature on the campfire-themed float. But the two sleuths are sure the mysterious death wasn't an accident. Teaming up with their ever-resourceful friend, Trista Bottoms, the girls trade their high tops for high heels and go undercover as helpers to the snooty Royal Court girls. They’ve got plenty of suspects: Barb Lund, angry that her daughter didn’t make the Royal Court; bitter Luna Vista Middle School Principal Katz, who was passed over for Festival president; and Festival vice president Lee, whose business would have benefitted from an unexpected change in leadership. But as the girls go deeper into the world of the Winter Sun Festival, their friendship is tested—and as they get closer to solving the case, their search for the truth becomes more dangerous than they ever could have imagined...
