I Minus 72

Ted Mason, the new President-elect, has seventy-two days until his inauguration. There’s a lot to do, but it’s all overshadowed by a possible threat on his life. A torn piece of paper with his name, another name, and his inauguration date was found on the dead body of a former Soviet informant.
In fact, fourteen Soviet-era, Eastern European informants are dead. People are dying at an alarming rate. Too many to be a coincidence. All were part of the same intelligence network initially set up decades ago within the Defense Intelligence Agency (DIA) by now-retired Air Force Colonel Grant Thurmond. Only he has the inside knowledge necessary to stop the assassin.
Unfortunately, his name is also on the torn piece of paper.
Recalled to active duty by Presidential authority, Thurmond must search for the killer while the killer searches for him. Will he be able to find the assassin? More importantly, will he be able to do it in 72 days?
