And, earlier, how Holmes describes the man who hid Silver Blaze, Silas Browne (?), is precisely apropos here, for ElMusk, "A more perfect compound of the bully, coward, and sneak, I've seldom met." And then, "A faker like him knows many a dodge." He reminds me of those tall, blond, high-cheekboned folks that began appearing in South America in the 1940s, with the thick German accent and no past to speak of.
This is, of course, from the Granada Productions Holmes serieses starring the one, the only, the inimitable, Jeremy Brett.
Of course, you can find many ElMusks in the various bad guys throughout the serieses, as there are lots of rich guys being very naughty, indeed.
