"That is right; that is the spirit in which to approach the problem. And, remember, that what may appear to you to be the most trivial detail may prove to be of the utmost importance to our case. For instance, I am going to ask you to do something now that may produce big results. I want you to get your grandfather's permission to use the top room over the tower."

"But what can I want it for? It is useless to me."

"At present, yes; but later it will be useful. You require it for an observatory. You are going to try to repair the big telescope. You are enthusiastic on the subject, you are hot-foot to get to work at once. There is nothing but lumber there."

"Boxes belonging to Marion, uncle. Cases that have remained unpacked ever since she came over from India."

Ralph smiled in his most inscrutable manner.

"Mere trifles," he croaked. "But, there, I am one of the men who deny there are such things as trifles. You may lose a pin out of your watch, a trifle hardly visible to the eye a yard off. And yet your costly watch, with its marvelous mechanism, is useless without that 'trifle.' Now go."

An hour later and Geoffrey was busy in the corridor with the big telescope, the telescope that nobody had troubled about at Ravenspur for many years. Geoffrey, in his shirt sleeves, was polishing up the brasses. Vera was with her mother somewhere.

There had been no trouble in getting permission from Rupert Ravenspur. It was doubtful if he even heard Geoffrey's request. Everything the young people asked they got, as a rule. Why not, when a day might cut off their lives and their little pleasures for all time! The head of the family was fast becoming a fatalist. So far as he was concerned, there was no hope that the terror would ever lift. He had escaped once; the next time the foe would not fail. But there would be rest in the grave.

Marion found Geoffrey in the corridor. The yellow and purple lights from the leaded windows filled the place with a soft, warm glow. Marion's dark hair was shot with purple; her white dress, as she lounged in a window seat, was turned to gold. She formed a wonderfully fair and attractive picture, if Geoffrey had only heeded it. But, then, Geoffrey had no eyes for any one but Vera.

"What are you going to do?" Marion asked. "Read your fortune in the stars? Get inspiration from the heavenly bodies to combat the power of darkness?"
