Shacklebolt looked strong enough to snap Beverly’s spine without a wand; but fortunately, Shacklebolt was one of those people who acted calm all the time. Beverly felt safe with "Shack," just as she now felt safe near Harry (even though Harry was three years younger than Beverly). Shacklebolt was wearing a suit and tie, instead of the long robes that magical men wore (and that Shacklebolt himself had been wearing, till he magically had changed them). Shacklebolt had showed Beverly an identification card that said he was an MI-5 agent, and this ID badge looked completely real to Beverly; but Miney had said that the badge was a magical forgery.
