This rose is mentioned in "Death of His Uncle" (1939) by CHB Kitchin:

"I confess that when I met Cousin Bill, I found him as uninteresting as the dinner, which, by the way, was eatable, but little more. I can’t remember his saying anything at all, except once, when the conversation came round to roses. Then he described, in a dull, deep voice, how his father—also a nursery gardener, I gathered—had tried to produce a really good white rose, with the pure white of Frau Karl Druschki, the perfect form of, say, Mabel Morse, and the vigorous but neat habit of Shot Silk. He went through the newer white roses one by one, pointing out the faults in each of them. His chief complaint was that most of them weren’t really white. And the few that were really white had other defects. It was a not uninteresting lecture, but Uncle Hamilton, who, perhaps, had heard the story before, listened impatiently, and finally cut Cousin Bill short by saying: ‘Well, I bet it cost your father a lot of money. And he didn’t produce anything to beat Clarice Goodacre. You stick to the commercial side of your business, and leave the fancy stuff alone. Now what about some coffee outside, before we start bridge?’"
