Text: A Washington Post book critic and Exley's literary executor, Yardley is said to use scant evidence--such as numerous late-night phone calls from Exley from 1975 to 1992--to draw conclusions about Exley's self-absorption and ambiguous sexuality.
Entailment: Yardley has used unreliable evidence to speculate about sexual orientation of Exley.
Contradiction: Yardley has solid evidence such as footage of Exley performing fellatio on a man.
