"Don’t mention it," Comstock stays, slapping Graves heartily on the shoulder. "That is why I try to give my men broad discretion. It has been my opinion for quite some time that Waterhouse is badly in need of some relaxation. He concentrates a little too hard on his work. Sometimes I frankly cannot tell whether he is saying something very brilliant, or just totally incoherent. And I think you have made a pivotal, Sergeant Graves, a pivotal contribution to today’s meeting by having the good sense to stand off long enough for Waterhouse’s affairs to be set in order." Comstock realizes that he is breathing very fast, and his heart is pounding madly. Perhaps he overdid the benzedrine?
