When business owner and personal friend Jay Weather is murdered, all the evidence points to P.I. Mark Logan as the killer. Logan knows he didn't do it...or does he? It is his .357 found next to the body, and he can't remember where he was, or what he did the night of the murder. There is one thing Logan does know. Jay came to see him the day before he died, and his friend was clearly scared and confused. So scared, Jay had signed over his business to Logan for safe keeping, and so confused he was seeing imaginary green parrots, and having strange compulsions to do things completely out of character...like changing his will.
Suddenly Logan starts finding more frequent gaps in his memory, and uncharacteristic overpowering urges that he finds impossible to ignore. But that's not all - now the police have discovered another corpse.
