"I _do_ hope the superintendent's set doesn't have rabbits' ears," said Mrs. Mimms, dialing the super's apartment again to check. "Hooking these up to a regular aerial is so much easier." The superintendent's set luckily had an outside antenna and by manipulating certain dials, the Destinyworker traced it out and up to the roof. Pressing a button marked TRACER LIGHT, she left the set in operation and made her way up to the top floor of the apartment house. Taking the fire exit to the roof, Mrs. Mimms found herself among a forest of TV aerials. However there was a small circle of light cast about one of them and she went to it and attached the filter. Returning to her apartment, Mrs. Mimms went immediately to bed. She would have liked a last cup of tea before retiring, but she was too tired to fix it. The telephone woke the time traveler at half past ten the next morning. She answered it sleepily. It was a young mother, Mrs. Mimms' first customer. Could Mrs. Mimms _possibly_ come that night? The voice sounded desperate, then relieved when Mrs. Mimms answered Yes, she would be there. Remembering that she had had nothing to eat since her own century, Mrs. Mimms hurried below to the delicatessen and purchased some Danish pastry. She looked forward to a cup of strong tea. As she waited for the water to boil, she switched on the apparatus and dialed once or twice across the band. At that hour most of the apartments were silent. Wives were attending to cleaning or washing and the children had been sent out to play. Leaving the apparatus for a minute, Mrs. Mimms made her tea. When she returned there was a burst of static on the loudspeaker, then a loud childish voice and images took shape on the screen. "I'm captain of this spaceship, Ronnie Smith," insisted the taller of the two youngsters. "You gotta do like I say. We're the first guys on this planet, see? We got cut off from the ship by the monsters and we only got another half hour of oxygen left. We gotta shoot our way back. Let's go, Lieutenant Smith." "Ah, you're always the captain," muttered Lt. Smith mutinously, though inaudibly under his F.A.O. Schwartz plastic helmet. The two Earthlings advanced cautiously across the parking lot in the rear of the apartment building, mowing down the aliens like flies with their atomic ray guns. "Ah-ah-ah-ah-ah. See me get that one, Smith?" screamed the captain murderously. "Right in the belly, look at the guts. Ah-ah-ah-ah. Big spiders, about twenty feet tall. There's some more. Make every shot count, Smith. We gotta make the ship before they do." "I just blasted five of 'em with one shot," bragged Lt. Smith, leveling his pistol at a particularly large alien and watching it dissolve.
