 Which word doesn't describe Tolliver?
On the bulletin board, Tolliver's name stood out beside the number of one of the airtight tractors used between the dome city and the spaceport, or for hauling cross-country to one of the mining domes. "Sure," agreed Tolliver thinking, Ohmigod! He enlarged upon other dangers to be encountered on the satellite, taking care to impress the newcomer with the daredeviltry of John Tolliver, driver of "missions" across the menacing wastes between dome and port. He stared unbelievingly at Betty, and Tolliver thought he muttered something about "just landed." Tolliver found himself dumped on the floor of an empty office in the adjoining warehouse building.
