In the Scottish university city of Dundee, life and all its complications are proceeding much the same as usual.

The recklessly brilliant DI Donna Davenport, struggling to hide a secret from police colleagues and get over the break-up with her partner, is in trouble with her boss for a fiery and inappropriate outburst to the press.

DI Evanton, an old-fashioned, hard-living misogynistic copper has been newly demoted for thumping a suspect, and transferred to Dundee with a final warning ringing in his ears and a reputation that precedes him.

And in the peaceful, rolling Tayside farmland a deadly store of MIC, the toxin that devastated Bhopal, is being illegally stored by a criminal gang smuggling the valuable substance necessary for making cheap pesticides.

An anonymous tip-off starts a desperate search for the MIC that is complicated by the uneasy partnership between Davenport and Evanton and their growing mistrust of each other's actions.

Compelling and authentic, Toxic is a tense and fast paced crime thriller.
