The House of Mammon by Fred M. White

There was no sign of flinching about Sairson. The danger had come and he was ready to meet it. He saw pretty clearly the line the prosecution intended to take. They wanted to establish a motive for the attack upon his life, and had made a successful effort. As John Sairson he had not incurred Givanni's enmity, but when he stood confessed as John Blaydon, it was a different thing altogether. For this was the man against whom Anita Givanni had a bitter grievance.

Sairson would have gone a long way to prevent this exposure, but the thing had been done. All the cunning schemes and elaborate precautions of years were swept away. He did not trouble himself to inquire who had betrayed him--he wasted no time on idle speculations. The dramatic suddenness of the exposure gave him fresh courage. He faced black and hostile looks undaunted.
