In The Highland Falcon Thief: Adventures on Trains #1, a middle-grade series starter from MG Leonard and Sam Sedgman, a young boy is swept up in an investigation to uncover the perpetrator of a jewel theft.

When eleven-year-old Harrison "Hal" Beck is forced to accompany his travel-writer uncle on the last journey of a royal train, he expects a boring trip spent away from video games and children his age.

But then Hal spots a girl who should not be on board, and he quickly makes friends with the stowaway, Lenny. Things get even more interesting when the royal prince and princess board for the last leg of the journey―because the princess's diamond necklace is soon stolen and replaced with a fake! Suspicion falls on the one person who isn't supposed to be there: Lenny.

It's up to Hal, his keen observation, and his skill as a budding sketch artist to uncover the real jewel thief, clear his friend's name, and return the diamond necklace before The Highland Falcon makes its last stop.

In this second book of the middle-grade Adventures on Trains series, amateur sleuth Hal Beck travels to the U.S. with his uncle to ride a famous train―the California Comet―and stumbles on a new mystery to solve, in M.G. Leonard and Sam Sedgman's Kidnap on the California Comet...

After his adventure on the Highland Falcon, amateur sleuth Hal Beck is excited to embark on another journey with his journalist uncle. This time, they're set to ride the historic California Comet from Chicago to San Francisco.

Hal mostly keeps to himself on the trip, feeling homesick and out of place in America. But he soon finds himself drawn into another mystery when the young daughter of a billionaire tech entrepreneur goes missing!

Along with new friends―spunky 13-year-old Mason and his younger sister, Hadley―Hal races against the clock to find the missing girl before the California Comet reaches its final destination.

In this third book of the middle-grade Adventures on Trains series by M. G. Leonard and Sam Sedgman, amateur sleuth Hal Beck travels to South Africa with his uncle to a ride a famous train...and stumbles onto a murder mystery!

Following his adventure on the California Comet, artist and amateur sleuth Hal Beck is looking forward to another railway journey with Nat, his journalist uncle―this time riding the historic Safari Star through South Africa. Then the already eventful journey becomes even more so when one of their fellow passengers dies on board!

Accident . . . or murder?

With help from a new friend, Winston (and his mongoose, Chipo), Hal is determined to figure out if a murder has really taken place and, if so, who among a long list of suspects is the killer―all before the Safari Star arrives at its final destination.

Danger at Dead Man's Pass, the fourth book in the middle grade Adventures on Trains series by M.G. Leonard and Sam Sedgman with black-and-white illustrations from Elisa Paganelli, finds amateur sleuth Hal Beck dealing with a family curse and a possibly haunted railway line.

Curses aren't real...are they?

Twelve-year-old artist and budding railway detective Hal Beck is back on the case. This time, he and his Uncle Nat have been invited by Baron Essenbach to help solve a mystery...a supernatural one. Because Essenbach thinks there might be something going on with his wife's family, the Kratzensteins. They are powerful German railway tycoons who are very rich―and maybe cursed.

After all, legend says that an ancestor of the Kratzensteins once made a deal with the devil.

Hal and Uncle Nat agree to help going undercover to spend time with the family and investigate. As more and more weirdness happens, can Hal solve this paranormal puzzle before it's too late?
