The fifth title in this ingenious series of Sherlock Holmes Escape Books, The Adventure of the Two Flying Scotsmen, is an exhilarating combination of escape room, puzzle book and adventure story.

In this latest tale, Sherlock Holmes and Watson find themselves trapped on a Flying Scotsman bound for Edinburgh after being mistakenly led to believe that Sherlock is needed in Scotland to thwart a plot against the Queen. Readers will quickly discover that the plot in motion is rigging a rail race between the two Flying Scotsmen that day. A race where the Queen's son Bertie has ill-advisedly lent money to a small gang of ne'er-do-wells within the household of the socialite Daisy Greville. A woman with whom Bertie is having a secret affair.

With Sherlock trapped on one train and the gang rigging the other, readers will face many challenges to thwart the gang and prevent the news of Bertie's affair from reaching the public. Something readers must do before the race between the two locomotives concludes in Edinburgh.

The readers, like Sherlock, must solve the puzzles aboard the train and alert the authorities before reaching the stop at York. However, this isn't the only challenge the readers will face as anti-monarchists - aware of the gang's plot, also seek to destroy the monarchy's reputation by attempting to derail one of the trains so the money can be lost and Bertie's secrets can be exposed.

With the reputation of royalty at stake, readers will follow Sherlock as he strives to solve the puzzles and prevent the royal scandal from breaking. If Holmes fails to solve the mystery, the train and the monarchy's reputation could be catastrophically derailed.
