Stranded on a mountain in Peru after the crash of a luxury airship, John Boarhog has only one mission on his mind: reuniting with his mentor and guardian, Inspector Toadius McGee. John’s convinced that if he makes his way to a plume of smoke in the distance, the great detective will be waiting. The only problem is there’s a whole rainforest between them.

After battling their way through the Amazon, John and his friends find a train—The Peruvian Express—and its glittering owner, Oro Del Rey, the Golden King, who offers them passage as they continue to search for their loved ones.

Soon John’s investigation goes off the rails when he’s asked to help to locate an infamous Object of Doom. But he’s not the only one on the hunt. . . .

Hoping to intercept the Mauve Moth before they execute their next great heist, Inspector Toadius McGee and his protégé John Boarhog book passage on the H.M.R.A.S. Bouteille—a luxury cruise liner airship. But alas, there will be no clear skies ahead. A committee from the Society of Sleuths is also aboard, ready to put John through his first trial to gain full membership, despite Toadius’s objections. Furious with his mentor, John falls in with the Hive, a group of kids obsessed with using social media for fame. They see how valuable he is, even if Toadius doesn’t. 

But when both the Mauve Moth and Shim-Sham resurface, each with their own nefarious aims, will the detective duo be able to see past their disagreements to, once again, save the day? 

The second book in The Curious League of Detectives and Thieves series, S.O.S. is a hilarious, high-flying, heart-pounding mystery adventure readers won’t be able to put down.
Book 1
Hilarious, non-stop adventure, a mysterious jewel heist, and a detective team like no other make this a must-have middle grade series starter. Perfect for fans of A Series of Unfortunate Events and Enola Holmes.

After twelve-year-old John Boarhog’s mom dies, he refuses to be schlepped off to the Jersey Home for Boys, where kids are forced to make skinny jeans for hipsters and are fed nothing but kale. Instead, he makes himself a snug home in the ceiling of the New York Museum of Natural History, where he reads anything he can get his hands on and explores the artifacts after-hours.

But when a rare Egyptian ruby—the highlight of the museum’s new exhibit—goes missing, John is accused of the crime. That is until the unpredictable Inspector Toadius McGee sweeps in to wrestle control of the case, certain that the true culprit is a notorious criminal he’s been tracking for years.

John quickly becomes the Watson to Toadius’s Holmes as they race from Broadway to back alleys to a speak-easy that only serves root beer. And along the way, John uncovers secrets about his own past, including that he’s a lot more involved in this web of endearing ne’er-do-wells than he ever could have imagined.
