But, if I reached no satisfactory conclusion, my cogitations had one useful effect; they occupied my mind to the exclusion of that unfortunate draught of tea. Not that I had been seriously uneasy after the first shock. The quantity that I had swallowed was not large⁠—the tea being hotter than I cared for⁠—and I remembered that, when I had thrown out the lump of sugar, I had turned the cup upside down on the table; so there could have been nothing solid left in it. And the lump of sugar was in itself reassuring, for it certainly would not have been used in conjunction with any less conspicuous but more incriminating form of poison. That lump of sugar was now in my pocket, reserved for careful examination at my leisure; and I reflected with a faint grin that it would be a little disconcerting if it should turn out to contain nothing but sugar after all.
