But who was the Tiger? That was the most important question of all, barring only the whereabouts of the spoil. Who in all Baycombe kept under his modest hat the brain that had conceived and organised that stupendous coup? Bloem, Bittle, and Carn could be ruled out. That left the highly respected Sir Michael Lapping, the pleasant but brainless Mr. Lomas-Coper, the masculine Miss Girton, and the two retired and retiring I.C.S. men, Messrs. Shaw and Smith. Five runners, and a darned sight too little help from the form book. The Saint frowned. Tackling the problem in the light of the law of probability, every one of the possibles had to be ruled out, which was manifestly absurd. Wiring into it with any mystery story as a textbook, it at once appeared that Lapping was too far above suspicion to escape it, Algy was too frankly brainless to be anything but the possessor of the Great Brain, Agatha Girton was quite certain to turn out to be a man masquerading as a woman, and Shaw and Smith kept too much in the background to avoid the limelight. Which once again was manifestly absurd. And the order of seniority was of little assistance, for Bloem, Algy, Agatha Girton, and Bittle had all been living in Baycombe for some time before the Tiger smashed the strong-room of the Confederate Bank of Chicago—on a general estimate, Simon reckoned that the Tiger had spent at least five years over that crime. And that was a deduction that confirmed the Saint’s respect for the Tiger’s brilliance without going any distance to aid the solution of the mystery of the Tiger’s identity.
The Saint had got no further when Bittle returned and drew Bloem to one side. Simon could only hear a word here and there. He gathered that the Tiger was furious with Bittle for taking so long and making so much noise over capturing the prisoner; that Bittle would have liked to see the Tiger do better himself; that the Tiger had an Idea. There followed some mutterings that the Saint did not catch, and then came one sentence quite distinctly:
“The Tiger says we must let him go.”
Bloem gave an exclamation, and Bittle talked further. The Saint’s brain was whirring like a buzz-saw. Let him go, with so much given away and most of the court cards in their hands? Simon wondered if he had heard aright, but in a moment Bittle left Bloem and came over to confirm the sensitiveness of the Saint’s auditory nerves.
“It is getting late, Mr. Templar,” said the millionaire, “and we all feel that the festivities have been kept up long enough. Pray do not let us detain you any longer.”
“Meaning?” suggested Simon, with as much levelness as he could command.
“Meaning that you are free to go as soon as you like.”
Bittle looked hard at the Saint as he spoke, and the malevolence that glittered in his eyes belied the geniality of his speech. Bittle was clearly upset at having to carry out such a command. He barked an order, and the escort of roughnecks sidled out of the room, closing the door behind them. Bloem was fidgeting with his tie, and he kept one hand in a pocket that bulged heavily.
“That’s nice of you,” drawled the Saint. “You won’t mind if I take Anna, will you?”
He strolled coolly over to the secretaire, jerked open a drawer, and retrieved the knife that they had taken from him, slipping it back into the sheath under his sleeve. Then he faced the two men again.
