Edgar Wallace & Edgar Wallace 
The Three Oak Mystery [EPUB ebook] 

‘MURDER is neither an art nor a science, it is an accident, ‘ said Socrates Smith, and Lex Smith, his younger brother, his most devoted admirer and his dearest trial, grinned sardonically.
A greater contrast between the two men it would be difficult to imagine. ‘Soc’ Smith, was nearing fifty and was a lean, tall, stooping man with a lined face—it seemed to be carved by careless hands from a block of seasoned teak. A tiny iron grey moustache lay above a firm mouth, set tight and straight.
Lex was twenty-five years his junior, and two inches shorter. But so straight was his back that most people thought the brothers were of the same height, and if they had had to say off-hand which was the taller, would, with little hesitation, have named the good-looking boy.
