" There just didn’t seem anyone else who could have done it. I thought perhaps he’d gone a little mad.” “Did he ever seem to you a little—what shall I say—queer?” “Oh no. Not queer in that way. He was just shy and awkward as anyone might be. The truth was, he didn’t make the best of himself. He hadn’t confidence in himself. "

― Agatha Christie , Mrs. McGinty's Dead (Hercule Poirot, #25)
