No man lives or has ever lived who has brought the same amount of study and of natural talent to the detection of crime which I have done. And what is the result? There is no crime to detect, or, at most, some bungling villainy with a motive so transparent that even a Scotland Yard official can see through it." I was still annoyed at his bumptious style of conversation; I thought it best to change the topic.

* 1928 , (Virginia Woolf), :

She could stand it no longer. It was full of prying old women, she said, who stared in one's face, and of bumptious young men who trod on one's toes.
