Headcase
Jack Heath2022

A Chinese astronaut is found dead in a NASA training environment in Houston, Texas. No one can explain how he got there. Amid fears of a diplomatic catastrophe, the CIA dispatches Timothy 'Hangman' Blake to investigate, because a convicted kidnapper works in the facility - someone Blake put away a long time ago.
Blake is deeply insane, afflicted by terrible urges he can barely control - but he's also brilliant. Zara, his beautiful and deadly CIA handler, suspects a secret Chinese spacecraft is surveilling the United States, but Blake can see something much more sinister is going on. Something connected to the kidnapping seven years ago, to the technologies being developed at NASA, and to the serial killer known as the Texas Reaper.
Will Blake survive long enough to uncover the truth? And if he does, will anyone even believe him?
