About

Nils B. Grevillius, b.1963, is not to be confused with his better known Swedish Composer Cousin, Nils Grevillius (1893-1970).

Grevillius is an author and private investigator who has spent much of his life in Pasadena, California, a tony town part of Metropolitan Los Angeles.

Never one much for convention, Grevillius took a job in a saloon at age 13, and gravitated away from school, eventually dropping out. From age 17-24, Nils Grevillius was in the US Army, pulling three tours in Korea as an infantryman and Counterintelligence Operative.

Recruited to the Pinkerton Services’ Wilshire Office in the late 1980s, Grevillius conducted protective, criminal, and undercover operations for the Pinkerton Service, America’s oldest Private Investigative company.

In the early 1990s, Nils went into private practice as a Private Detective, keeping offices in Pasadena. With his move, Nils Grevillius was involved in the investigations of Bruce McNall, renegade owner of the Los Angeles Kings, David Hemmings and John Daly, operators of Hemdale pictures for the US Bankruptcy Trustee.

The late 1990s saw Nils Grevillius investigating the Wonderland Avenue Murders, or more correctly, the cover-up of the murders and the connections between Los Angeles’ City Hall and Organized Crime. It is the Wonderland Case for which Nils is best known.

Grevillius has conducted investigations in support of journalists, such as New York City Author John Connelly (Spy Magazine), and Legs McNeil, with the latter’s well known works on punk rock and pornography.

In 2003, awaiting two hookers who were thought to be witnesses in a Hollywood kidnapping, Grevillius took up writing, writing “City of Devils” in his Copenhagen hotel room.

In ensuing months, Grevillius wrote “Skulldiggery” and “Sub Rosa”, works which were published in 2013.

Nils Grevillius is an auto-didact, who admits that which he attended six different colleges, in three different countries, over six or seven odd years, he may be awarded an AA Degree were he to take up college again for two full years.
