Which made the problem of getting back home a delicate one indeed...._ [Illustration] Time Fuze By Randall Garrett Illustrated by Paul Orban Commander Benedict kept his eyes on the rear plate as he activated the intercom. "All right, cut the power. We ought to be safe enough here." As he released the intercom, Dr. Leicher, of the astronomical staff, stepped up to his side. "Perfectly safe," he nodded, "although even at this distance a star going nova ought to be quite a display." Benedict didn't shift his gaze from the plate. "Do you have your instruments set up?" "Not quite. But we have plenty of time. The light won't reach us for several hours yet. Remember, we were outracing it at ten lights." The commander finally turned, slowly letting his breath out in a soft sigh. "Dr. Leicher, I would say that this is just about the foulest coincidence that could happen to the first interstellar vessel ever to leave the Solar System." Leicher shrugged. "In one way of thinking, yes. It is certainly true that we will never know, now, whether Alpha Centauri A ever had any planets. But, in another way, it is extremely fortunate that we should be so near a stellar explosion because of the wealth of scientific information we can obtain. As you say, it is a coincidence, and probably one that happens only once in a billion years. The chances of any particular star going nova are small. That we should be so close when it happens is of a vanishingly small order of probability." Commander Benedict took off his cap and looked at the damp stain in the sweatband. "Nevertheless, Doctor, it is damned unnerving to come out of ultradrive a couple of hundred million miles from the first star ever visited by man and have to turn tail and run because the damned thing practically blows up in your face." Leicher could see that Benedict was upset; he rarely used the same profanity twice in one sentence. They had been downright lucky, at that. If Leicher hadn't seen the star begin to swell and brighten, if he hadn't known what it meant, or if Commander Benedict hadn't been quick enough in shifting the ship back into ultradrive--Leicher had a vision of an incandescent cloud of gaseous metal that had once been a spaceship. The intercom buzzed. The commander answered, "Yes?" "Sir, would you tell Dr. Leicher that we have everything set up now?" Leicher nodded and turned to leave. "I guess we have nothing to do now but wait." When the light from the nova did come, Commander Benedict was back at the plate again--the forward one, this time, since the ship had been turned around in order to align the astronomy lab in the nose with the star.
