"Martin Vanger had contrived his private torture chamber with great care. On the left were chains, metal eyelets in the ceiling and floor, a table with leather straps where he could restrain his victims. " (Pg. 480)
With both Martin Vanger and his father Gottfried Vanger being revealed as serial killers, this brings up the question of "What Creates a Serial Killer?"
"Statistically, the average serial killer is a white male from a lower-to-middle-class background, usually in his twenties or thirties. Many were physically or emotionally abused by parents. Some are very intelligent and have shown great promise as successful professionals. " (http://www.crimelibrary.com/serial_killers/notorious/tick/victims_1.html)
Martin and Gottfried can fall into all of these statistics of what makes a serial killer. They are white men that are successful professionals and Martin was directly influenced by Gottfried and some might say even emotionally abused, although not as evident as Harriet, and this created the monster that Martin would become later in life.
