"Smoke screen is wickedly intense and action packed with everything you'd want in a thriller." Robert Dugoni, New York Times and #1 Amazon Bestselling Author. When a string of knockout-gas attacks followed by military-style kidnappings and vanishing witnesses hit Silicon Valley, Detectives Darcy Lynch and Erik Sorensen fear they’re facing a national security threat. But soon things turn personal for Darcy, his girlfriend’s sister is missing, and the more they dig, the less she seems to be the ordinary college student everybody thought she was. Could she be entangled with the mastermind behind the attacks? Set against the backdrop of Silicon Valley’s unrelenting startup culture, where fortunes can rise and fall in an instant, Smoke Screen is the sequel to Elin Barnes's debut novel, Justification for Murder. - from Amzon
