Lethal Experiment is a Donovan Creed novel. Locke does it again with another story of the slightly amoral Creed and his cohorts. It says something about his world when Donovan Creed won't even drink from a glass his friends poured, if they don't taste it first.
Creed is still working part-time for little Victor and it's beginning to have an effect on him. Could he have a conscience after all? Will he get married? Will he get killed? Read the book and find out. It's well worth the time. Very highly recommended.
