Oberst Karl Bauer

Oberst Karl Bauer is the main villain of Henderson's Boys book four, Grey Wolves.

Biography
Shortly after the stabbing of a German soldier, Bauer finds thirteen-year-old Marc Kilgour hiding among some dustbins and takes him into custody. As the soldiers' killer was drunk, this gives Bauer an excuse to arrest racketeer Madame Mercier on a trumped-up charge of inciting violence. Back at his headquarters, Bauer tortures Mercier by dunking her head in an ice bath. During this interrogation, Bauer is informed of an attack on a train Depot. Believing communist partisans to be responsible, Bauer orders a crackdown on local communists and has one prisoner shot for every train damaged, as well as having the depot guard hanged with piano wire alongside the aforementioned murderer.
