The Wessex Hotel in Los Angeles is a Victorian hotel, built in 1898 at a height of 16 floors, including a 13th floor. Early in its history, serial killer Avery Block brought his friends to the 13th floor of the Wessex where he proceeded to kill them with a fire ax hoping to achieve immortality by the taking of others' lives. Due to the murders, the 13th floor was sealed off in October 1901 and a frieze was erected around the building covering the floor. Ninety years later, Traveler's Review magazine sends Elaine Kalisher to write a travel article.
