He was about Rand's own age and height; he had a smooth-shaven, tight-mouthed face, adorned with bushy eyebrows, each of which was almost as heavy as Rand's mustache. It was a face that seemed tantalizingly familiar, and Rand puzzled for a moment, then nodded mentally. Of course he had seen a face like that hundreds of times, in newsreels and news-photos, and, once in pre-war Berlin, its living double. Rudolf Hess. He wondered how much deeper the resemblance went, and tried not to let it prejudice him. Nelda greeted him with a trowelful of sweetness and a dash of bedroom-bait. Gladys waved him to a vacant seat at her right and summoned the maid who had been serving breakfast. After Rand had indicated his preference of fruit and found out what else there was to eat, he inquired where the others were. "Oh, Fred's still dressing; he'll be down in a minute," Nelda told him. "And Geraldine won't; she never eats with her breakfast." Varcek winced slightly at this, and shifted the subject by inquiring if Rand were a professional antiques-expert. "No, I'm a lily-pure amateur," Rand told him. "Or was until I took this job. I have a collection of my own, and I'm supposed to be something of an authority. My business is operating a private detective agency." "But you are here only as an arms-expert?" Varcek inquired. "You are not making any sort of detective investigation?" "That's right," Rand assured him. "This is practically a paid vacation, for me. First time I ever handled anything like this; it's a real pleasure to be working at something I really enjoy, for a change." Varcek nodded. "Yes, I can understand that. My own work, for instance. I would continue with my research even if I were independently wealthy and any sort of work were unnecessary." "Tell Colonel Rand what you're working on now," Nelda urged. Varcek gave a small mirthless laugh. "Oh, Colonel Rand would be no more interested than I would be in his pistols," he objected, then turned to Rand. "It is a series of experiments having to do with the chemical nature of life," he said. Another perfunctory chuckle. "No, I am not trying to re-create Frankenstein's monster. The fact is, I am working with fruit flies." "Something about heredity?" Rand wanted to know. Varcek laughed again, with more amusement. "So! One says: 'Fruit flies,' and immediately another thinks: 'Heredity.' It is practically a standard response. Only, in this case, I am investigating the effect of diet changes. I use fruit flies because of their extreme adaptability. If I find that I am on the right track, I shall work with mice, next." "Fred Dunmore mentioned a packaged diabetic ration you'd developed," Rand mentioned. "Oh, yes." Varcek shrugged. "Yes. Something like an Army field-ration, for diabetics to carry when traveling, or wherever proper food may be unobtainable. That is for the company; soon we put it on the market, and make lots of money. But this other, that is my own private work."
