On a cold night in January 2001, the idyllic community of Dartmouth College was shattered by the discovery that two of its most beloved professors had been hacked to death in their own home. Investigators searched helplessly for clues linking the victims to their murderer or murderers. A few weeks later, across the river, in the town of Chelsea, Vermont, police cars were spotted in front of the house of a high school senior. Soon, the town discovered the incomprehensible reality that two of Chelsea's brightest and most popular sons, were now fugitives, wanted for the murders.

Jimmy Joste was a powerhouse in the oil and gas industry, but he was a weakling when it came to his gorgeous, athletic, longtime lover, Rhonda Glover. Addicted to her sexual prowess and madly in love, Joste gave her homes, cars, cash, and a $350,000 engagement ring. Their 15 years of passion and excess ended the day Rhonda drove directly from a shooting range to the Austin home they once shared. After pumping 10 bullets into him from a Glock 9mm, she stood over Joste's blood-splattered body and shot him six more times, twice below the waist.

In September 2011, Erik Weissman and two friends were murdered in a brutal triple homicide in Waltham, Massachusetts. The case went unsolved for months and then years, with no discernible leads.

As Susan began digging, and as the Boston Marathon bombing exposed startling new leads, the case led her down a tangled and sometimes dangerous path to the truth.

In 1911 two British heiresses, Claire and Dora Williamson, read a brochure about a revolutionary fasting treatment that promised a lifetime of good health. The sanatorium in the village of Olalla, west of Seattle, was surrounded by a beautiful forest, sparkling waters and fresh air. The sisters agreed it sounded perfect and exactly the restorative holiday they needed. But within a month of arriving, under the supervision of Doctor Linda Burfield Hazzard, Claire and Dora began to realise the frightening truth – they were not patients but prisoners at the isolated sanitorium.
