This rich man had hired Jack and arranged for him to get something called a Plague Pass: a large document in that Gothickal German script with occasional excursions into something that looked like either Latin (when it was desirable to invoke the mercy and grace of God) or French (for sucking up to King Looie, only one rung below God at this point). * By flourishing this at the right times, Jack was able to carry out his mission, which was to go into Strasbourg; proceed to the rich man's dwelling; wash off the red chalk crosses that marked it as a plague-house; pry off the deals he'd nailed over the doors and windows; chase out any squatters; fend off any looters; and live in it for a while. If, after a few weeks, Jack hadn't died of the plague, he was to send word to this rich man in the country that it was safe to move back in.
