Simon Dean was a telesalesman for a life-assurance company, or that's what he probably still thought he was, though one of his last acts before leaving work, according to the rigorously backed-up e-mail system his company maintained, had been to send a resignation note to his boss, accompanied by a detailed account of Simon's intentions regarding the boss's teenage daughter.

If extroversion drugs lead every stranger, every telesalesman to address me by my first name (too many do already) and intrude a feigned intimacy, give me Grant Wood!

'Eeerrr... sorry wrong number,' came the confused reply from the telesalesman.
