Investigator Kendra Michaels—formerly blind and now with uniquely insightful observational skills in the tradition of Sherlock Holmes—returns in this action-packed novel from the #1 New York Times and Edgar Award-winning writing duo Iris Johansen and Roy Johansen.   When Kendra Michaels receives a cryptic message from her sometimes-paramour Adam Lynch, she concludes that he must be in extreme danger—the kind where he can’t trust his FBI and Justice department colleagues to rescue him. Lynch has saved Kendra’s life during past investigations so she’s immediately willing to put everything on the line for him.    With her heightened senses, honed in the dark before she regained her eyesight in a cutting-edge surgical procedure, Kendra knows she can do what the federal agents cannot. So along with private investigator Jessie Mercado, Kendra is soon following the first intriguing clue to London.   What they find there will lead to a chase with deadly stakes because Lynch is willing to risk it all to protect something he believes is bigger than himself. Something that could change life for everyone on the planet…if only they live long enough to share the truth.
