Trail of Poison

Some secrets are toxic...

When environmentalist Max Edwards is found dead on the bank of the River Thames, his widow turns to rookie private detective Emily Swanson for help.

But as Emily investigates, a case of accidental death quickly takes a dangerous turn. Max isn’t the only one to die in strange circumstances, a mother and child are missing, and all of the evidence points to the mysterious Valence Industries.

Out of her depth and with the body count rising, Emily must seek the help of an unlikely ally. Because if she doesn’t uncover the truth about Max Edwards soon, more innocent people will die.

A fast-paced murder mystery, Trail of Poison is the third book in this gripping British crime series featuring private investigator Emily Swanson.
