Detective Tom Lange (of LAPD, retired) is the co-author of the
as-yet-unpublished book "Four On The Floor", which chronicles the murders of the "Wonderland Gang" in LA's Laurel Canyon in 1981. Adult film actor
John Holmes was tried and later acquitted for his involvement in the killings, as were would-be gangster
Eddie Nash, and his cohort Gregory DeWitt Diles, who died in 1995.
