And so we must accept Charles Peace as a remarkable character, whose unquestioned gifts as a man of action were squandered on a criminal career; neither better nor worse than a great number of other persons, whose good fortune it has been to develop similar qualities under happier surroundings. There are many more complete villains than the ordinary criminal, who contrive to go through life without offending against the law. Close and scientific investigation has shown that the average convicted criminal differs intellectually from the normal person only in a slightly lower level of intelligence, a condition that may well be explained by the fact that the convicted criminal has been found out. Crime has been happily defined by a recent and most able investigator into the character of the criminal(12) as "an unusual act committed by a perfectly normal person." At the same time, according to the same authority, there is a type of normal person who tends to be convicted of crime, and he is differentiated from his fellows by defective physique and mental capacity and an increased possession of antisocial qualities.(13) (12) "The English Convict," a statistical study, by Charles Goring, M.D. His Majesty's Stationery Office, 1913. (13) Murderers--at least those executed for their crimes--have not for obvious reasons been made the subject of close scientific observation. Their mental capacity would in all probability be found to be rather higher than that of less ambitious criminals. How does Peace answer to the definition? Though short in stature, his physical development left little to be desired: he was active, agile, and enjoyed excellent health at all times. For a man of forty-seven he had aged remarkably in appearance. That is probably to be accounted for by mental worry. With two murders on his conscience we know from Sue Thompson that all she learnt of his secrets was what escaped from him in his troubled dreams--Peace may well have shown traces of mental anxiety. But in all other respects Charles Peace would seem to have been physically fit. In intellectual capacity he was undoubtedly above the average of the ordinary criminal. The facts of his career, his natural gifts, speak for themselves. Of anti-social proclivities he no doubt possessed his share at the beginning, and these were aggravated, as in most cases they were in his day, by prison life and discipline.
