"It was, of course, a very ticklish point in law whether the housemaid's evidence could be accepted. You see, she was quoting the words of a man since dead, spoken to another man also dead. There is no doubt that had there been very strong evidence on the other side against Percival Brooks, Mary Sullivan's would have counted for nothing; but, as I told you before, the judge's belief in the prisoner's guilt was already very seriously shaken, and now the final blow aimed at it by Mr. Oranmore shattered his last lingering doubts.
"Dr. Mulligan, namely, had been placed by Mr. Oranmore into the witness-box. He was a medical man of unimpeachable authority, in fact, absolutely at the head of his profession in Dublin. What he said practically corroborated Mary Sullivan's testimony. He had gone in to see Mr. Brooks at half-past four, and understood from him that his lawyer had just left him.
"Mr. Brooks certainly, though terribly weak, was calm and more composed. He was dying from a sudden heart attack, and Dr. Mulligan foresaw the almost immediate end. But he was still conscious and managed to murmur feebly: 'I feel much easier in my mind now, doctor--have made my will--Wethered has been--he's got it in his pocket--it is safe there--safe from that--' But the words died on his lips, and after that he spoke but little. He saw his two sons before he died, but hardly knew them or even looked at them.
"You see," concluded the man in the corner, "you see that the prosecution was bound to collapse. Oranmore did not give it a leg to stand on. The will was forged, it is true, forged in the favour of Percival Brooks and of no one else, forged for him and for his benefit. Whether he knew and connived at the forgery was never proved or, as far as I know, even hinted, but it was impossible to go against all the evidence, which pointed that, as far as the act itself was concerned, he at least was innocent. You see, Dr. Mulligan's evidence was not to be shaken. Mary Sullivan's was equally strong.
"There were two witnesses swearing positively that old Brooks' will was in Mr. Wethered's keeping when that gentleman left the Fitzwilliam mansion at a quarter past four. At five o'clock in the afternoon the lawyer was found dead in Phoenix Park. Between a quarter past four and eight o'clock in the evening Percival Brooks never left the house--that was subsequently proved by Oranmore up to the hilt and beyond a doubt. Since the will found under old Brooks' pillow was a forged will, where then was the will he did make, and which Wethered carried away with him in his pocket?"
