Mission: Mayhem is the 93rd book in the The Hardy Boys Casefiles series.
The Hardys have taken the ultimate challenge: a rigorous pre-astronaut training program at the Space and Rocket Center in Huntsville, Alabama. But in a course designed to simulate the actual conditions of space flight, the boys discover that the risks are dangerously real. Someone on the team is out to scuttle the mission...with potentially deadly consequences!
Launching their own investigation, Frank and Joe are drawn to the very cutting edge of space-age technology. But time is running out and the stakes are sky-high. They've entered a world where there's zero margin for error, a world where each new act of sabotage puts an explosive new spin on terror!
- Mission: Mayhem is part 1 of a two part story arc involving Perry Housman. Perry Housman reappears in the next Casefiles book, A Taste For Terror, although the events of that book have nothing to do with the events or location of this book.
