The prospect of Galahad's writing his reminiscences causes a good deal of consternation among England's well-established upper-class because he had, in younger days, been "a notable lad about town," a partier, drinker, prankster, and ladies' man, and his stories are liable to embarrass his former comrades, most of whom have grown into respectable gentlemen.
One particularly embarrassing story concerns Sir Gregory Parsloe-Parsloe and prawns, though we never learn many details of the incident, other than that it took place at Ascot, "the year Martingale won the Gold Cup".
[2] His wildness makes him very popular with the members of the Blandings servants hall, who feel he sheds lustre on the castle, but less so with his sisters, who find him something of an embarrassment, particularly when recalling stories of their now-respectable friends.
Thereafter he becomes a regular visitor, frequently involved in the intrigues and conspiracies that invariably surround the place, generally filling the role of level-headed and resourceful saviour and the champion of youth and romance.
[5] In the two Blandings novels after Summer Lightning in which he does not play a part, his shoes are ably filled by his fellow-Pelican Uncle Fred (Lord Ickenham).
