I came across the following passage in the book The Broken Vase by Rex Stout. It turns out to be a clue. One wonders if this is an accurate reference to a particular catalog.

It sounds like a good name, doesn't it? I suppose the lawyers would discourage naming an actual source.

The plot point here is that someone had to change hobbies to disguise how he used his funds. And thus his cover begins to unravel.

Tecumseh Fox was one of Rex Stout's secondary leads (of course no one could replace Nero Wolfe and Archie Goodwin). Fox was in ways a mirror Wolfe: he kept a farm in the country, not orchids in the city, and did his own detecting solo.
