Pulse — Edna Buchanan

If Daniel Alexander had not committed suicide, Miami businessman Frank Douglas would never have lived to see his forty-fifth birthday. Now, with a donated heart beating strong and sure in his chest, Frank has been given a second chance-but no peace. Disturbed by nagging feelings of guilt and uncertainty, he feels an intense need to discover all he can about his mysterious late benefactor-a desire that is drawing Frank and the dead man's beautiful, enigmatic widow across a nation toward shocking revelations about Alexander's affairs...and deep into something corrupt and twisted and deadly. And suddenly the new life Frank Douglas has been granted is in serious peril, threatened by secrets, lies, human savagery and greed...and by the true dark nature of the organ that is now pumping the lifeblood through his body.
