Nor did Graham, nor even Paula, imagine that Dick--the keen one, the deep one, who could see and sense things yet to occur and out of intangible nuances and glimmerings build shrewd speculations and hypotheses that subsequent events often proved correct--was already sensing what had not happened but what might happen. He had not heard Paula's brief significant words at the hitching post; nor had he seen Graham catch her in that deep scrutiny of him under the arcade. Dick had heard nothing, seen little, but sensed much; and, even in advance of Paula, had he apprehended in vague ways what she afterward had come to apprehend. The most tangible thing he had to build on was the night, immersed in bridge, when he had not been unaware of the abrupt leaving of the piano after the singing of the "Gypsy Trail"; nor when, in careless smiling greeting of them when they came down the room to devil him over his losing, had he failed to receive a hint or feeling of something unusual in Paula's roguish teasing face. On the moment, laughing retorts, giving as good as she sent, Dick's own laughing eyes had swept over Graham beside her and likewise detected the unusual. The man was overstrung, had been Dick's mental note at the time. But why should he be overstrung? Was there any connection between his overstrungness and the sudden desertion by Paula of the piano? And all the while these questions were slipping through his thoughts, he had laughed at their sallies, dealt, sorted his hand, and won the bid on no trumps. Yet to himself he had continued to discount as absurd and preposterous the possibility of his vague apprehension ever being realized. It was a chance guess, a silly speculation, based upon the most trivial data, he sagely concluded. It merely connoted the attractiveness of his wife and of his friend. But--and on occasional moments he could not will the thought from coming uppermost in his mind--why had they broken off from singing that evening? Why had he received the feeling that there was something unusual about it? Why had Graham been overstrung? * * * * * Nor did Bonbright, one morning, taking dictation of a telegram in the last hour before noon, know that Dick's casual sauntering to the window, still dictating, had been caused by the faint sound of hoofs on the driveway. It was not the first of recent mornings that Dick had so sauntered to the window, to glance out with apparent absentness at the rush of the morning riding party in the last dash home to the hitching rails. But he knew, on this morning, before the first figures came in sight whose those figures would be.
