The Devils Call Twice.

The Devil Calls Twice.
The third in the Lee Hunter Crime Files.
Lennard Post was recently released from prison after serving twenty-two years for murdering his wife. Post contacts Hunter asking for help to clear his name for the murder he maintains he did not commit.
Hunter reluctantly agrees to take on the case, but things aren’t as simple as they first appear to be. It emerges that twenty-two years ago Post was also linked to several sadistic killings, for which he was never charged.
Soon the vicious slayings start once again. Could it be that Lennard Post is now resuming his murderous activities, with one more brutal killing each day he remains at large.
Hunter has only one week to untangle the mystery before even more people lose their lives.
