The Agent

Cade Garrett wakes up in a hospital bed and learns that is the sole survivor of a near-fatal car crash; and that he was lucky to escape with just a head injury.
When he returns to his home, he finds that the locks have been changed.
He dials the only number in his phone - Harlan O'Keefe's - but it goes to voicemail.
Cade suddenly finds all his loose ends have been tied up; his contracts are concluded, and his bank account is extremely healthy to the tune of ten million dollars.
Money he has no recollection of having before.
Cade's life becomes enshrined in a mystery which almost takes his last breath to unravel.
