The Oxford Murders

“There is no way of finding a single absolute truth”

An old woman is found dead in Oxford, and a note left behind carries a mathematical symbol, the first of what looks like a series. Martin (Elijah Wood), a graduate student, and Arthur Seldom (John Hurt), a professor of logic, start reading the clues together. Álex de la Iglesia sets the two of them side by side, the younger man trusting the elder's mind and the elder watching how far that trust will go.
