Bright and early the next morning it was off to the Gare du Nord to catch a comfortable and speedy train to the Netherlands. The mission here was to give an after-dinner talk to the assembled Princeton Club of the Netherlands, meeting in the Hague. Our delightful host was Henk Gajentaan, a retired Dutch diplomat of ambassadorial rank, who awaited us on the train platform in an orange-and-black scarf of the kind normally donned only for the P-rade. The dinner took place, and so did the talk. The Princeton Club of the Netherlands has the distinction of being the most erudite such group I have yet encountered. But there was an entirely different high point to our visit, for Henk had arranged a special treat for us.
