This is a day that should be marked with honor on the calendar of all Rex Stout fans. It is the day that Archie Goodwin met the love of his life, Lily Rowan. This happens in the first chapter of the sixth Nero Wolfe novel, Some Buried Caesar, and it is certainly one of the most memorable openings in that long series.
The fat sleuth is in upstate New York, heading to a flower show, when his car has an accident. Wolfe and Archie take a short cut through a pasture, which turns out to have a bull in it. Archie has to run and tumble over a fence, nearly getting mangled to death by an angry beast, and as he struggles to his feet he hears a woman applauding and cheering as if he were a circus act. And that, of course, is Lily Rowan.
But my favorite line in the book is from Wolfe: "If you regard it as a rational project to find a legitimate nocturnal pickwasher, go ahead." You had to be there.
