“For the secret of this apparent miracle—which was not intended to be a mystery at all-lies in a very simple fact. It is the fact that one man's raincoat looks very much like another man's raincoat.
“We don't write our names in raincoats. They are not of a distinctive colour. They are made only in a few stock sizes; and we know that Harry Brooke “in height and weight,' as Rigaud says, was like his father. Among Englishmen especially it is a point of pride, even of caste and gentlemanliness, for his raincoat to be as old and disreputable as possible without becoming an actual eyesore. When next you go into a restaurant, observe the line of bedraggle objects hanging on coat-pegs and you will understand.
“Our friend Rigaud here never dreamed he had sen Mr. Brooke in two different coats at two different times. Since Mr. Brooke was actually dying in his own coat, nobody else ever suspected. Nobody that is, except Fay Seton.”
Professor Rigaud got to his feet and took little short steps up and down the room.
“She knew?” he demanded.
“Undoubtedly.”
“But after I saw her for a moment at the door of the tower, and she ran away from me, what did she do?”
“I can tell you,” Barbara said quietly.
Professor Rigaud, fussed and fussy, made gestures as though he would try to shush her.
“You mademoiselle? And how would it occur to you to know?”
“I can tell you,” answered Barbara simply, “because it's what I should have done myself.” Barbara's eyes were shining with a light of pain and sympathy. “Please let me go on! I can see it!
“Fay went for a swim in the river, just as she said she did. She wanted to feel cool; she wanted o feel clean. She'd really-really fallen in love with Harry Brooke. IN circumstances like that it'd be easy” Barbra shook her head, “to convince yourself . . . well! That the past was the past. That this was a new life.
“And then she'd just crept up to the tower, and heard. She heard what Harry had said about her. As though instinctively he knew it was true! As though the whole world could look at her and know it was true. She'd seen Harry stab his father, but she didn't think Mr. Brooke was seriously hurt.
“Fay dived into the river, and floated down towards the tower. There were no witnesses on that side, remember! And—of course!” cried Barbara. “Fay saw the brief-case fall from the tower!” Barbara afire with this new realization, turned to Dr. Fell. “Isn't that true?”
Dr. Fell inclined his head gravely.
“That, ma'am, is whang in the gold.”
“She dived down and got the brief-case. She carried it with her when she left the river, and hid it in the woods. Fay didn't know what was going on, of course; she didn't realize until later what must have happened.” Barbara hesitated. “Miles Hammond told me, on the way here, what her own story was. I think she never realized what was going on until . . .”
“Until,” supplied Miles, with an intensity of bitterness, “until Harry Brooke came rushing up to her, exuding hypocritical shock, and cried out, 'My God, Fay, somebody's killed Dad.' No wonder Fay looked a trifle cynical when sh told me!”
“One moment!” said Professor Rigaud.
After first giving the impression of hopping up and down, though in fact he did not move, Professor Rigaud raised his forefinger impressively.
“In this cynicism,” he declared, “I begin to see a meaning for much. Death of all lives, yes! This woman,”--he shook his forefinger--”this woman now possesses evidence which can send Harry Brooke to the guillotine!” He looked at Dr. Fell. “Is it not so?”
“For you also,” assented Dr. Fell, “Whang in the gold.”
“In this brief-case,” continued Rigaud, his face swelling, “are the stones used to weigh it and Harry's raincoat stained with blood inside where his father has worn it. It would convince any court. It would show the truth.” He paused, considering. “Yet Fay Seton does not use this evidence.”
“Of course not,” said Barbara.
“Why do you say of course, mademoiselle?”
“Don't you see?” cried Barbara. “She'd got to a state of-of tiredness, of bitterness, where she could practically laugh? It didn't affect her any longer. She wasn't even interested in showing up Harry Brooke for what he was.
“She, the amateur harlot! He, the amateur murderer and hypocrite! Let's be indulgent to each other's foibles, and go our ways in a world where nothing will ever come right anyway. I—I don't want to sound silly, but that's how you really would feel about a situation like that.
“I thin,” said Barbara, “she told Harry Brooke. I think she told him she wasn't going to expose him unless the police arrested her. But, in case the police did arrest her, she was going to keep that brief-case with ts contents hidden away where nobody could find it.
“And she did keep the brief-case! That's it! She kept it for six long years! Sh brought I to England with her. It was always where she could find I. Bu she never had any reason to touch it, until . . . until . . .”
Barbara's voice trailed off.
Her yes looked suddenly and vaguely frightened, as though Barbara wondered whether her own imagination had carried her too far. For Dr. Fell, with wide-eyed and wheezing interest, was leaning forward in expectancy.
“Until--?” prompted Dr. Fell, in a hollow voice like wind along the Underground tunnel. “Archons of Athens! You're doing it! Don't stop there! Fay Seton never had any reason to touch the brief-case until . . .?”
But Miles Hammond hardly heard this. Sheer hatred welled up in his throat and choked him.
“So Harry Brooke,” Miles said, “Still got away with it?”
Barbara swung round from Dr. Fell. “How do you mean?”
“His father protected him,” Miles made a fierce gesture, “even when Harry bent over a dying man and mouthed out, 'Dad, who did this?' Now we learn that even Fay Seton protected him. “Steady, my boy! Steady!”
“The Harry Brookes of this world,” said Miles, “always get away with it. Whether it's luck, or circumstances, or some celestial gift in their own natures, I don't pretend to guess. That fellow ought to have gone to the guillotine, or spent the rest of his life on Devil's Island. Instead it's Fay Seton, who never did the least harm to anybody, who . . .” His voice rose up. “By God, I wish I could have met Harry Brooke six years ago! I'd give my soul to have a reckoning with him!”
“That's not difficult,” remarked Dr. Fell. “Would you like to have a reckoning with him now?”
An enormous crash of thunder, rolling in broken echoes over the roof-tops, flung ts noise into the room. Raindrops blew past Dr. Fell as he sat by the window: not quite so ruddy of countenance now, with his unlighted pipe in his hand.
Dr. Fell raised his voice.
“Are you out there, Hadley?” he shouted.
Barbara jumped away from the door; staring, she groped back to stand at the foot of the bed. Professor Rigaud used a French expletive not often heard in polite society.
And then everything seemed to happen at once.
As a rain-laden breeze came in at the windows, making the hanging lamp sway over the chest-of-drawers, some heavy weight thudded against the outside of the closed door to the passage. The knob twisted only slightly, but frantically, as though hands fought for it. Then the door banged open, rebounding against the wall. Three men, who were trying to keep their feet while fighting, lurched forward in a wrestling-group which almost toppled over when it banged against the tin box.
