"We don’t have to walk right up to their door." Michel pointed out. "We can go as sightseers, Rennes-le-Château gets a reasonable number of fruitcakes and flutters turning up to see the diabolic doorkeeper and all the other weirdness. Not many, but, slot, we could be researchers for a trid company. Or anything. We can at least scan it out and decide our next move from there. We can keep our research on the rails if we base ourselves in Clermont-Ferrand. Hell, we’d only have to go on a day trip. And there’s one other thing; it would get us out of London and keep us on the move. Away from those not-terribly-pleasant people keeping an eye on us."
