    Not only was he hated by the whole world, even some of his own military commanders didn’t like him. Most leaders around the world rely on one, maybe two bodyguards to keep them safe. Even the President of the United States today has only one or two teams of security personnel; while there may be many men and women who take turns to protect their leader, the numbers are not as big as you would expect it to be. We will look at the origins of a number of bodies, such as the ‘Sturmabteilung’ or the SA, the Schutzstaffel (the SS) and the many other sub-sections of the SS such as the FBK, the LSSAH, etc., all of which were tasked with protecting Hitler. From the background, we will move on to individual accounts of men who served on these teams – they were Hitler’s personal bodyguards and some stayed with him until the very end. Humanity’s depraved nature came to fore with these men; despite having a master who was truly mad and ravenous for blood, they served him loyally. Was it because they were also as depraved as he was?

    Picking up where Brontë left off, the year is now 1851, and Jane’s life has finally settled into a comfortable pattern. She and her beloved Edward Rochester have married, and have an infant son. But Jane soon finds herself in the midst of new challenges and threats to those she loves… Jane can’t help but fret when a letter arrives from Adèle Varens—Rochester’s ward and Jane’s former pupil, currently at boarding school—warning that the girl’s life is in jeopardy. Although it means leaving her young son and invalid husband, and despite never having been to a city of any size, Jane feels strongly compelled to go to London to ensure Adèle’s safety. But almost from the beginning, her travels don’t go as planned—she is knocked about and robbed, and no one believes that the plain, unassuming Jane could indeed be the wife of a gentleman. Even when she arrives at the school, the headmistress takes her for an errant new teacher, and berates her for her late arrival. Most shocking to Jane is the discovery that Adèle’s roommate has recently passed away under very suspicious circumstances, yet no one at the school seems concerned. Taking advantage of the misunderstanding, she decides to pose as the missing instructor—and soon uncovers several unsavory secrets, which may very well make her the killer’s next target…
