Christopher Marlowe.

Christopher Marlowe was a poet and playwright born in Canterbury in 1564 and died on the 30th of May 1593. He went to The Kings School in Canterbury, and then went on to Corpus Christi College in  Cambridge to do a BA degree in 1584 and later MA. It is said that while at Corpus Christi he may have been influenced religiously by the beliefs of Francis Kett, who was burned in 1589 after being accused of heresy.

While doing his Masters degree Marlowe would frequently not attend, and was absent so much that it went against the rules of the university which put his degree in jeopardy. Marlowe got his degree thanks to the Privy Council (Queen's council) who allowed him his degree because of 'good service' to the Queen which then fuelled speculation that Marlowe was a spy for Sir Francis Walsingham (part of a spy service for the Queen). According to www.marlowe-society.org/ Marlowe was recruited by Walsingham as a 'part-time secret service agent'.
    Marlowe was arrested in 1592 for the counterfeiting of coins, but was not charged, even after being sent to the Lord Treasurer, which fits with the spy idea in the sense that at that time you were likely to be executed for that sort of crime, but he was let off.

Marlowe was arrested on 20th of May 1593 on a charge of atheism, and therefore heresy. He was granted bail despite the seriousness of the crime, and had to report daily to an officer of the court. On the 30th May Marlowe was spending the day in Deptford with Robert Poley (an experienced government agent), Ingram Frizer (the personal servant and business agent of Thomas Walsingham, the cousin of Sir Francis Walsingham), and Nicholas Skeres (often assisted Poley, and was often associated with Walsingham). Marlowe, Skeres, Poley and Frizer are all linked by Sir Francis Walsingham, a spy.
 It is said that after the four spending the day together, there was an argument between Frizer and Marlowe over a bill, which led to Marlowe wounding Frizer with Frizer's dagger, and the fight culminating in Frizer stabbing Marlowe just above the right eye, killing him. Marlowe was buried in an unmarked grave in the churchyard of St Nicholas Deptford.

There are claims that Marlowe's death was faked and that he is in fact William Shakespeare, who was born around two months after Marlowe. A.D Wraight analysed Shakespeare's sonnets and found links between him and Marlowe. More about this can be found on http://www.marlowe-society.org/marlowe/life/exile1.html.
