"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."

Dunmore had come in while Varcek was speaking and had seated himself beside his wife.

"Don't let him kid you, Colonel," he said. "Anton's just as keen about that dollar as the rest of us. I don't know what he's cooking up, up there in the attic, but I'll give ten-to-one we'll be selling it in twenty-five-cent packages inside a year, and selling plenty of them.... Oh, and speaking about that dollar; how did you make out with Gresham and his friends?"

"I didn't. They'd expected to pay about twenty thousand for the collection; Rivers's offer has them stopped. And even if they could go over twenty-five, I think Rivers would raise them. He's afraid to let them get the collection; Pierre Jarrett and Karen Lawrence intended using their share of it to go into the old-arms business, in competition with him."

"Uh-huh, that's smart," Dunmore approved. "It's always better to take a small loss stopping competition than to let it get too big for you. You save a damn-sight bigger loss later."
