"There are more ways of doing it than one," Anstruther said presently. "In this instance we can take a hint from the daily papers. Supposing that the bank was mysteriously robbed--the safes forced open and all that kind of thing?"

"Yes, and the whole thing exposed in twenty minutes," Carrington said, bitterly. "The robbing and gagging of cashiers has been slightly overdone lately. I can't call a single case to mind in which the scheme has not fallen to the ground. Take the case of those stolen banknotes, for instance. And even supposing that nothing could be proved against one, there is always a large section of the public ready to regard the trouble as nothing more than a mere swindle. An affair like that would be the finishing touch; it would ruin the bank's business utterly."

"And incidentally save your skin," said Anstruther, significantly. "Oh, no; this is going to be a much more artistic affair than that. If you could get me a plan of the bank premises, including the safes and the cellars and all that kind of thing, I believe I could hit upon a scheme ingenious enough to deceive the police and gain you the sympathy of the British public."

Carrington shook his head wearily. He had expected something much more brilliant and original from Anstruther than this.

"The plan you want would take days to prepare," he said, "to say nothing of the fact----"

Carrington jumped to his feet joyfully. His moody face cleared, and something like a smile shone on his features. "What a fool I am!" he cried. "Why, I have the very thing on the premises; in fact, I have two copies. It was only a few months ago that the bank premises were thoroughly restored and a fresh set of strong rooms added. I feel positively certain that in my safe here I have two sets of tracings of the architect's plans. I'll get them for you. Only I hope you won't make the same blunder over this business as you did at the affair of the man whom we will call Nostalgo Seymour."

Anstruther laughed unpleasantly. Jack's companion, listening intently from his hiding place amongst the ferns, gripped his companion by the arm. "That's me," he whispered, with almost a suppressed chuckle. "I am the man they speak of as Nostalgo Seymour."

Jack pressed the arm of his fellow conspirator by way of acknowledgment. He was far too interested in what was going on inside the brilliantly-lighted room to care to talk; indeed, he had forgotten the presence of his comrade altogether. He could see that Anstruther had risen to his feet and was pacing the room, evidently nettled by Carrington's remark. "If you want to be friends, don't mention that matter to me again," he said. "It is the one failure of my life. To get Seymour out of the way is imperative. I trusted the matter to Padini, and he failed me."

"I would have trusted nothing to Padini," Carrington said.

"Oh, yes, you would," Anstruther growled. "Especially if he had done so many artistic jobs in the same line for you. But I did not know, unfortunately, till too late, that the little rascal has been drinking more lately than was good for him. The fact is, he has lost his nerve. And yet he might have felt himself justified in believing that his mission had been attended with complete success--but go and get your plans. I will have a good look at them now, and I will call to see you to-morrow at the bank as if I came on business, and you shall show me all over the premises. It will be surprising, indeed, if I cannot show you some safe way out of the present difficulty."
