Carson

It has always been thought, people diagnosed with Autism Spectrum Disorder (ASD) are born without emotions and feelings.  They were a bit like Spock from Star Trek   ̶   analytical and logical.  To the world, it seems, they can't love, and in turn, they can't care for anyone.  People with ASD make the best assassins.

Carolyn Johnston, the eight-year-old daughter of the recently deceased prostitute Freda Johnston, finds herself a captive of the men who murdered her mother.  As fate would have it, her life now depends on an assassin with ASD.

His name is Carson.
