Death by Chocolate - Nick Williams

When sweetness turns bitter.

What begins as a series of unexplained poisonings becomes one of the world's most deadly spree's of homicide.

Special Agent Aisha Monroe sees the pattern before anyone else does. A killer who doesn't rush, doesn't improvise, and doesn't leave anything to chance.
If she has any hope of stopping him, she needs to learn how he thinks.

Because Elliot Graves wasn't born this way.

He was shaped by the world he now seeks to punish by turning sweetness into something deadly.
