The rocket went off, and the Haywire Queen's pilot did some fancy work until the inert rocket ship entered the space lock above. Larry Timkins emerged, holding his head between his hands. "It's murder," he said. "Downright murder!"

"What's murder?"

"Manipulating that fire-breathing gargoyle. Y'know how the regular drive takes hold all at once? Well, this thing sort of hangs fire. There's a bit of a lag—ever so little—since the jets are sheer mechanical and the time-function requires that the mechanical linkages from lever-turn to fuel-release, ignition, and ultimate movement—well, they act in considerably less time than the electrogravitic drive."

"Do you have to use it again?"

"Nope. I planted the spotter-generators and—picked up a souvenir of Soaky. Look," and he pulled a piece of crystal from his spacesuit pouch and dropped it on the table.

"Dirty looking hunk of glass," said Hammond. "Going to use it for a paperweight?"

"It'd go better on the gal friend's finger, but I'm going to sell it and lay away the profits for my edification and amusement. It'll assay four karats if it's worth a dime, and that ain't quartz."

"Diamond?" asked Hammond in surprise.
