Was this the cipher, of which he had never received the key? The papers he had hoped to find must be hidden elsewhere. No doubt in some place whose whereabouts was indicated, if he could only understand it, by the incomprehensible message he held.
He stared at it for some minutes in an endeavour to find the translation; then, reflecting that this was neither the time nor place for deciphering cryptograms, he placed it carefully in an inner pocket, and after a hasty exploration of the passage beyond which did not reveal anything interesting except from an archaeological point of view, he thoughtfully mounted to the room above.
Closing the trap-door, and making sure that everything in the library was left as he had found it, Gimblet made his exit from the castle in the same manner as he had entered it, and groped his silent way home through the darkness.
A convenient creeper made it easy to climb on to the porch of Lady Ruth's house, now wrapped in peaceful slumber; and so in at his own window once more. The noise of the wind, which had now freshened to the strength of half a gale, drowned any sound of his return, and he lost no time in getting to bed and to sleep. The puzzle must keep till to-morrow. It was one of Gimblet's rules to take proper rest when it was at all possible, for he knew that his work suffered if he came to it physically exhausted.
