The one thing that impressed itself upon Monk as he looked over the papers a third time, reading the principal pieces aloud to Hester, was that the amounts of profit were not undue.

“The Baltimores must be comfortably off,” she observed. “But it is not really a fortune.”

“No,” he agreed wryly. “Not by railway standards, I suppose.”

Memory teased him that Dundas had been accused of defrauding for much larger profits than anything written here. It was only glimpses so brief they were gone again before he could understand them. They might have no connection with the present issue, but something in them could be the key, the one element still missing. And there was something that would tie them all together and make sense of them, but it floated always just beyond his reach, melting into shapelessness one moment, on the verge of identity the next. He grasped for it, and it melted into fear without meaning.

But there was another fear with very precise shape—Emma, to whom Katrina had written so frankly and in whom she had confided that she did not trust Monk. Who was she, and why had she not come forward? Someone would tell her Katrina had been murdered, friends, gossips, even possibly some lawyer with whom Katrina had entrusted her affairs. From his brief sight of her rooms, and the clothes she had worn to meet him, she was not without means.

If they corresponded with such candor then they were close, wrote frequently. There would surely be some note among Katrina’s papers—of her address, or at least something from which he could deduce where she lived.

She might even know more about Dalgarno than Katrina had told him, something to help Runcorn.

He must go back to her rooms. The question was: would it be wiser to go brazenly in daylight, lie that he had authority, or break in at night and trust to his skill not to be caught? Either way he had no honest explanation. Worst of all could be if he were caught having found Emma’s address, or some further damning letter from her.

But the risk of leaving it was too great, not only if Runcorn found it, but for the first time in his life that he could remember, his nerves were raw enough to betray him, to Hester at least, and it was she who mattered, even above the law.

He did not know if it was the braver of the two ways or not, but he chose to go by daylight. He would have a better chance of bluffing his way if he was questioned, and it was quicker. He wanted it over with. The waiting was almost as hard as the preparation and the doing.
