A Double Life: The Anatomy of a Premeditated Murder

By: Brottman, Mikita

With sharp psychological insight, the acclaimed author of Guilty Creatures digs into the sensational murder of Florida physician Teresa Sievers in this engrossing and unconventional true crime tale of holistic health, childhood doppelgangers, dark obsessions, and an open marriage.

Teresa and Mark Sievers led an enviable life in Bonita Springs, Florida. Teresa ran a thriving medical practice specializing in anti-aging and holistic care. Mark, a former nurse, managed the business while home-schooling their two daughters. Then, in June 2015, the unimaginable happened: Teresa was found murdered in their kitchen.

Mark's alibi was airtight. He and the girls were in New York on a family vacation. Initial signs pointed to a burglary gone wrong, but it soon became clear that the attack was targeted. The Sievers' friends and relatives were shocked. Teresa was a respected, charismatic physician, nicknamed a "modern-day Mother Teresa." Yet someone hated her enough to bludgeon her to death.

Cracks appeared beneath the glossy surface of the Sievers' lives. Teresa's quest for fame had led her to make some questionable decisions. The couple's marriage was passionate but volatile. Then there was Mark's childhood best friend, who looked so much like him that the two were often mistaken for twins. The bond between the two men was intense and intimate.

In a compelling narrative that goes beyond conventional true crime tropes, acclaimed author and psychoanalyst Mikita Brottman delves into a case that encompasses both obsessive love and deep hatred, probing the corrosive, sometimes deadly nature of both.
