A pleasant sense of retrospection settled upon him as he slowly undressed; and a pleasant sense of interest touched him as, crossing to the dressing-table, he caught sight of Chilcote's engagement-book--taken with other things from the suit he had changed at dinner-time and carefully laid aside by Renwick. He picked it up and slowly turned the pages. It always held the suggestion of a lottery--this dipping into another man's engagements and drawing a prize or a blank. It was a sensation that even custom had not dulled. At first he turned the pages slowly, then by degrees his fingers quickened. Beyond the fact that this present evening was free, he knew nothing of his promised movements. The abruptness of Chilcote's arrival at Clifford's Inn in the afternoon had left no time for superfluous questions. He skimmed the writing with a touch of interested haste, then all at once he paused and smiled. “Big enough for a tombstone!” he said below his breath as his eyes rested on a large blue cross. Then he smiled again and held the book to the light. “Dine 33 Cadogan Gardens, 8 o'c. Talk with L,” he read, still speaking softly to himself. He stood for a moment pondering on the entry, then once more his glance reverted to the cross. “Evidently meant it to be seen,” he mused; “but why the deuce isn't he more explicit?” As he spoke, a look of comprehension suddenly crossed his face and the puzzled frown between his eyebrows cleared away. With a feeling of satisfaction he remembered Lakely's frequent and pressing suggestion that he should dine with him at Cadogan Gardens and discuss the political outlook. Lakely must have written during his absence, and Chilcote, having marked the engagement, felt no further responsibility. The invitation could scarcely have been verbal, as Chilcote, he knew, had lain very low in the five days of his return home. So he argued, as he stood with the book still open in his hands, the blue cross staring imperatively from the white paper. And from the argument rose thoughts and suggestions that seethed in his mind long after the lights had been switched off, long after the fire had died down and he had been left wrapped in darkness in the great canopied bed. And so it came about that he took his second false step. Once during the press of the next morning's work it crossed his mind to verify his convictions by a glance at the directory. But for once the strong wish that evolves a thought conquered his caution. His work was absorbing; the need of verification seemed very small. He let the suggestion pass.
