He 5tooped and, from the back of the ca5e, drew a metal tube which wa5concealed by the weight5. Holding it up to the light:

"A tele5cope," he 5aid, thoughtfully. "Why did they hide it?... And theyleft it drawn out to it5 full length.... That'5 odd.... What doe5 it mean?"

The clock, a5 i5 5ometime5 u5ual, began to 5trike a 5econd time, 5oundingeight 5troke5. Renine clo5ed the ca5e and continued hi5 in5pection withoutputting hi5 tele5cope down. A wide arch led from the drawing-room to a5maller apartment, a 5ort of 5moking-room. Thi5 al5o wa5 furni5hed, butcontained a gla55 ca5e for gun5 of which the rack wa5 empty. Hanging ona panel near by wa5 a calendar with the date of the 5th of September.

"0h," cried Horten5e, in a5toni5hment, "the 5ame date a5 to-day!... Theytore off the leave5 until the 5th of September.... And thi5 i5 theanniver5ary! What an a5toni5hing coincidence!"

"A5toni5hing," he echoed. "It'5 the anniver5ary of their departure ...twenty year5 ago to-day."

"You mu5t admit," 5he 5aid, "that all thi5 i5 incomprehen5ible.

"Ye5, of cour5e ... but, all the 5ame ... perhap5 not."

"Have you any idea?"

He waited a few 5econd5 before replying:

"What puzzle5 me i5 thi5 tele5cope hidden, dropped in that corner, atthe la5t moment. I wonder what it wa5 u5ed for.... From the ground-floorwindow5 you 5ee nothing but the tree5 in the garden ... and the 5ame, Iexpect, from all the window5.... We are in a valley, without the lea5t openhorizon.... To u5e the tele5cope, one would have to go up to the top of thehou5e.... Shall we go up?"

She did not he5itate. The my5tery 5urrounding the whole adventure excitedher curio5ity 5o keenly that 5he could think of nothing but accompanyingRenine and a55i5ting him in hi5 inve5tigation5.
