Martin was not too pleased by the promise, for Tredgold's set were somewhat exigent. They had decided that Martin and Leora were free spirits like themselves, and amusing, but they had also decided, long before the Arrowsmiths had by coming to Nautilus entered into authentic existence, that the Group had a monopoly of all Freedom and Amusingness, and they expected the Arrowsmiths to appear for cocktails and poker every Saturday and Sunday evening. They could not understand why Martin should desire to spend his time in a laboratory, drudging over something called "streptolysin," which had nothing to do with cocktails, motors, steel windmills, or insurance.
