Choose your path, solve the puzzles, and catch the killer in this collection of three murder mysteries for kids ages 8-12 that challenge readers with logic problems, visual games, and a Choose Your Own Adventure hook.

When Arlo Banks solves a difficult puzzle in The Times, devised by an elderly Oxford professor, he wins a vast fortune. There's just one catch: he has to travel the world and write to the professor about his adventures. But enemies and killers lurk at every turn. From the Orient Express to the Nile River to British spy headquarters, join Arlo as he fights to find answers--and fights for his life!

As Arlo Banks, you choose what path to take and what puzzles to answer to solve each mystery. On the trail of a ruthless mafia godfather determined to evade capture...on a pleasure cruise where a passenger's death has a killing effect on the others on board...behind the scenes at British intelligence, where a dangerous traitor is selling government secrets.

It's up to you to uncover the truth. Be careful! Your next step could catch the killer--or be your last.
