He crossed the room and picked up the little book, which smelled faintly of jasmine. Momentary shame overcame him at thus stealing the secrets of an unknown girl. Necessity, however, left him no choice but to seize any chance of learning more of this ship of mystery and her invisible haunter. He broke the flimsy fastening. Linda Cross was the name written on the fly-leaf, in a firm, clear feminine hand. On the next page was the photograph, in color, of a girl, the brown-haired girl whose body Thad had discovered in the crystal coffer in the hold. Her eyes, he saw, had been blue. He thought she looked very lovely--like the waiting girl in his old dream of the silver tower in the red hills by Helion. The diary, it appeared, had not been kept very devotedly. Most of the pages were blank. One of the first entries, dated a year and a half before, told of a party that Linda had attended in San Francisco, and of her refusal to dance with a certain man, referred to as "Benny," because he had been unpleasantly insistent about wanting to marry her. It ended: "Dad said to-night that we're going off in the _Dragon_ again. All the way to Uranus, if the new fuel works as he expects. What a lark, to explore a few new worlds of our own! Dad says one of Uranus' moons is as large as Mercury. And Benny won't be proposing again soon!" Turning on, Thad found other scattered entries, some of them dealing with the preparation for the voyage, the start from San Francisco--and a huge bunch of flowers from "Benny," the long months of the trip through space, out past the orbit of Mars, above the meteor belt, across Jupiter's orbit, beyond the track of Saturn, which was the farthest point that rocket explorers had previously reached, and on to Uranus, where they could not land because of the unstable surface. * * * * * The remainder of the entries Thad found less frequent, shorter, bearing the mark of excitement: landing upon Titania, the third and largest satellite of Uranus; unearthly forests, sheltering strange and monstrous life; the hunting of weird creatures, and mounting them for museum specimens. Then the discovery of a ruined city, whose remains indicated that it had been built by a lost race of intelligent, spiderlike things; the finding of a temple whose walls were of precious metals, containing a crystal chest filled with wondrous gems; the smelting of the metal into convenient ingots, and the transfer of the treasure to the hold. The first sinister note there entered the diary: "Some of the men say we shouldn't have disturbed the temple. Think it will bring us bad luck. Rubbish, of course. But one man did vanish while they were smelting the gold. Poor Mr. Tom James. I suppose he ventured away from the rest, and something caught him."
