Robert Poley, or Pooley (fl.
 1568–1602) was an English double agent, government messenger and "agent provocateur" employed by members of the Privy Council during the reign of Queen Elizabeth I; he was described as "the very genius of the Elizabethan underworld".
 Poley is particularly noted for his central role in uncovering the so-called Babington plot to assassinate the Queen in 1586, and for being a witness of, and even a possible party to, the reported killing in self-defence by Ingram Frizer of the famous poet/dramatist Christopher Marlowe in May 1593.
Agent Provocateur is the fifth studio album by the British-American rock band Foreigner, released on December 7, 1984.
 The album was the band's first and only number one album in the United Kingdom, and it reached the top 5 in the United States.
 Although album sales were lower than their previous work in the U.S., it contains the band's biggest hit single, "I Want to Know What Love Is", which is their only #1 single in the UK and the U.S., staying at the top spot for three and two weeks respectively.
 The follow-up single, "That Was Yesterday", also proved to be a sizeable hit, peaking at #12 in the U.S.
 The album was certified Platinum in the UK by the BPI, and triple Platinum in the U.S. by the RIAA.
Provocateur (also released on video as Agent Provocateur) is a 1998 film directed by Jim Donovan, written by Roger Kumble, and starring Lillo Brancato Jr. and Jane March.
 The original score was written by Mark Nakamura and Mark Shannon.

 "I Want to Know What Love Is" has continued to garner critical acclaim, and is listed as one of Rolling Stone Magazine's greatest songs of all time at #479.
 The song is also featured in a number of films.

 The single reached number 12 on the "Billboard" Hot 100 chart, and also reached #4 on the Billboard Mainstream Rock chart and #24 on the Adult Contemporary chart.
 It also reached the Top 40 in the UK (#28), the Netherlands (#19), Switzerland (#29) and Germany (#31).

An agent provocateur (French for "inciting agent") is a person who commits, or who acts to entice another person to commit an illegal or rash act or falsely implicate them in partaking in an illegal act.
 An agent provocateur may be acting out of their own sense of duty or may be employed by the police or other entity to discredit or harm another group (such as a peaceful protest or demonstration) by provoking them to commit a crime, thereby undermining the protest or demonstration as a whole.
