Slow-moving detectives

Nero Wolfe was, of course, famously fat. "Inclined toward corpulence," one might have put it. Needless to say, he did not generally move very quickly. In fact, if he could keep from it, he did not move much at all. We also learn from the Sherlock Holmes stories that his brother, Mycroft, was not an energetic person. In fact, he makes several pointedly negative remarks about Sherlock's often-frenetic pursuit of criminals.
