Galahad - steady as a rock

It was never an easy matter to disconcert the Hon. Galahad. For half a century nursemaids, governesses, tutors, schoolmasters, Oxford dons, bookmakers, three-card trick men, jellied eel sellers, skittle sharps, racecourse touts and members of the metropolitan police force had tried to do it, and all had failed. It was an axiom of the old Pelican Club that, no matter what slings and arrows outrageous fortune might launch in his direction, Galahad Threepwood could be counted upon to preserve the calm insouciance of a pig on ice.
