The house next door, The Larches, has recently been taken by a stranger. To Caroline’s extreme annoyance, she has not been able to find out anything about him, except that he is a foreigner. The Intelligence Corps has proved a broken reed. Presumably the man has need of milk and vegetables and joints of meat and occasional whitings just like everybody else, but none of the people who make it their business to supply these things seem to have acquired any information. His name, apparently, is Mr. Porrott⁠—a name which conveys an odd feeling of unreality. The one thing we do know about him is that he is interested in the growing of vegetable marrows.

But that is certainly not the sort of information that Caroline is after. She wants to know where he comes from, what he does, whether he is married, what his wife was, or is, like, whether he has children, what his mother’s maiden name was⁠—and so on. Somebody very like Caroline must have invented the questions on passports, I think.
