“I have. As you advised. Unpleasant stuff. Like medicine. Burns your throat, too, and makes one as thirsty as the dickens. How anyone can mop it up, as you do, for pleasure, beats me. Still, I would be the last to deny that it tunes up the system. I could bite a tiger.”

“What did you have?”

“Whisky. At least, that was the label on the decanter, and I have no reason to suppose that a woman like your aunt—staunch, true-blue, British—would deliberately deceive the public. If she labels her decanters Whisky, then I consider that we know where we are.”

“A whisky and soda, eh? You couldn’t have done better.”

“Soda?” said Gussie thoughtfully. “I knew there was something I had forgotten.”

“Didn’t you put any soda in it?”

“It never occurred to me. I just nipped into the dining-room and drank out of the decanter.”

“How much?”

“Oh, about ten swallows. Twelve, maybe. Or fourteen. Say sixteen medium-sized gulps. Gosh, I’m thirsty.”

He moved over to the wash-stand and drank deeply out of the water bottle. I cast a covert glance at Uncle Tom’s photograph behind his back. For the first time since it had come into my life, I was glad that it was so large. It hid its secret well. If Gussie had caught sight of that jug of orange juice, he would unquestionably have been on to it like a knife.
