I have loved every book Gretchen Archer has written, but with Double Knot, she has outdone herself. Hearkening back to classic mystery writers of earlier decades, Double Knot is a taut, complex, witty, smart mystery with twists and turns that will keep you guessing ... while keeping you charmed and amused. Although the characters are sometimes thoroughly wacky, the story has many serious points to make.Breast cancer and its ravages and survivors. The relationship between mothers and daughters. The vulnerabilities of security in the real world. Tension builds from page one to the final word on the last page. I was not ready for the book to end. I wanted it to go on for many more pages.This is the book in which Davis Way becomes fully realized. Gains dimensions you knew were there, but had never been revealed. Emotional issues she must face and work through. With her mother along for the ride, it's time for both to confront their shared past and the painful secrets they have feared to acknowledge. They do it all under the most terrifying circumstances and with everything ... life and death ... at stake.In Double Knot, Ms. Archer has dived into deep water. If, like me, you've been wondering "Who is Davis ... really?", this is your golden opportunity to find out.This is no mere caper. Surviving this will require every ounce of Davis's creativity, intelligence, training, and techno-savvy. She's going to have to use it all to save her own life and the lives of those she loves.Gretchen Archer's ability to create an intricate story is hugely augmented by her ability allow her characters to evolve, develop previously unsuspected depths.The story is not merely exciting, complex, and deliciously edgy, it's also poignant and heartfelt.Do NOT miss this one!
