Private investigator, Jesse Clarke, thought sugar was such a friendly substance, until it appears in two of her cases for all the wrong reasons. Traces of sugar were connected to a bomb that blew up her client's Mercedes. Was the bomb meant to kill or was it just a warning of what is to come? And could sugar have duped the immune system of a client's mother over thirty years ago, resulting in death? Juggling the two cases-one in the present and one in the past-Jesse finds herself talking to the living and the dead to get results.
