The anthology "Pistols for Two" was first published in 1960. It has always, to me, seemed like a box of the finest sweets, a thrill to open, and a delight to savour the contents. The stories vary from the light and delicious Bath Miss to the mysterious and enjoyably chilling Night at the Inn. The very first heroine (I think) won by a gamble is Helen Morland in Hazard, and the mistaken identity in Full Moon is the epitome of charm.
I cannot recommend Heyer's only anthology highly enough, and I have always regretted that she produced just one collection of short stories. You may have gathered by now that I am one of Georgette Heyer's most ardent fans.
But I am not the only fan. Indeed, the delightful website Austenprose is currently hosting a whole month about Georgetter Heyer's work--reviews, articles, opinions. I recommend the event highly for information, giveaways (!), and great fun.
