Up the Line
by Robert Silverberg
Media: Mass market paperback
Cover art: (unknown)
Time travel spelled problems for the couriers of the Time Service. Shuttling backwards and forwards over the centuries they had to be wary of creating paradoxes — like meeting themselves watching the sack of Rome, or sleeping with their own ancestors.
Of course, it also gave them the chance to amass wealth by the discreet use of their prior knowledge. The penalties were fierce and the Time Police inplacable in their pursuit of lawbreakers. But it was still worth taking the risk.
Jud Elliott took it when he met the marvellous transtemporal paradox called Pulcheria. He couldn't resist her charms – the effects spanned generations, and set the Time Police on his trail!
UP THE LINE is one of the best time travel tales ever written, it's Robert Silverberg at his brilliant best.
