In 1965, nineteen-year-old Robin Farnham believes he ran over an old man but on stopping his car, finds no body, merely a gold bracelet of a snake biting its tail.

In 1981, sixteen-year-old Jane Foster is sexually abused by her adoptive father and attacks him before fleeing to London where she consults Dr Peter Lakmaker, a psychiatrist.

In 2021, now retired, Farnham is diagnosed with Alzheimer's and prescribed a drug on clinical trial. He attempts suicide but awakes in hospital to be told he is suspected of murder. Protected from the police by Dr Lakmaker, Robin is encouraged to write about his life to monitor the new drug's effectiveness.

Over a period of half a century, Robin and Jane's lives are interrelated although it is not until the year 2000, they finally meet. Robin's quest for the truth behind his involvement in not one, but three murders and Jane's tormented search for her birth parents and the close family relationship denied her as a child are muddied by the strangely prophetic Oroborous bracelet Robin wears and the appearance of the vengeance seeking Krait.

Separating fact from fiction has rarely presented more of a challenge, for the characters in the story or the reader.
