There are 32 full length novels featuring this pair, and over ten books which collect between two to four novellas per book. In And Four to Go (1958), there are four novellas; "Easter Parade" is the second novella in the book.
Jane Haddam wrote the introduction to the Bantam Crime Line edition of And Four to Go, and she is very complimentary of his short fiction here.
Someone looking for a chance to spend time with Wolfe and Archie at their most vivid could hardly pick a better volume than this one. Short detective fiction is often very frustrating. Restricted to a few thousand words, even the best of authors choke. Characters strongly drawn in the longer fictional forms become thin. Plots made intricate by twists and turns over the course of two hundred pages turn out to be obvious and feeble when confined to twenty. Maybe my third-grade teacher was right. Maybe Mr. Rex Stout was perfect. There are none of the weaknesses of your run-of-the-mill mystery story here.Of the novellas that I have read recently, the stories seem to focus more on the Wolfe - Goodwin relationship and less on the process of detecting. I do enjoy them just as much as the full length novels, but readers who want a good mystery might be disappointed.
The second paragraph of this story reads like Archie's job description . Archie is refusing to stoop to thievery, which he thinks is what Wolfe is after.
"If you wanted me to hook something really worth while, like a Mogok ruby, I might consider it. For what you pay me I do your mail, I make myself obnoxious to people, I tail them when necessary, I shoot when I have to and get shot at, I stick around and take every mood you've got, I give you and Theodore a hand in the plant rooms when required, I lie to Inspector Cramer and Sergeant Stebbins whether required or not, I even help Fritz in the kitchen in emergencies, I answer the phone. I could go on and on. But I will not grab an orchid from a female bosom in the Easter parade. There is--"Wolfe is not asking Archie to break the law and steal a very rare orchid, but he does want him to find someone who is "adroit, discreet, resolute, and reliable" for the job. The orchid will be worn in the Easter Parade, and Wolfe's lust for it will lead to problems for both him and Archie.
As Haddam mentions in her introduction, "Easter Parade" was first published in the April 16, 1957, issue of Look magazine, and it included color photos with clues to the mystery. You can see the illustrations that were in Look magazine at the Wikipedia page for this story or at The Wolfe Pack website.
Three of the stories in And Four To Go feature holidays, and I reviewed one of them, "Christmas Party," in December.
