The Killing of Hamlet

Visiting folksinger Sheil B. Wright, hired to sing old ballads, witnesses a real murder on stage during the premiere of a newly discovered Shakespeare play. The English village audience, however, see Sheil as the killer. To clear her name she must challenge hi-tech forensics.
After a second murder, Sheil finds a 400-year-old clue, and this makes her the killer's next target.
