"Revenge, Denzil. I have been the best friend you ever had in this cold, prosaic world. You have eaten my bread, drunk my claret, written my book, smoked my cigars, and pocketed my money. And yet, when you have an important piece of information bearing on a mystery about which I am thinking day and night, you calmly go and sell it to Wimp."
"I did-didn't," stammered Denzil.
"Liar! Do you think Kitty has any secrets from me? As soon as I discovered your two marriages I determined to have you arrested for—your treachery. But when I found you had, as I thought, put Wimp on the wrong scent, when I felt sure that by arresting Mortlake he was going to make a greater ass of himself than even nature had been able to do, then I forgave you. I let you walk about the earth—and drink—freely. Now it is Wimp who crows—everybody pats him on the back—they call him the mystery man of the Scotland Yard tribe. Poor Tom Mortlake will be hanged, and all through your telling Wimp about Jessie Dymond!"
"It was you yourself," said Denzil, sullenly. "Everybody was giving it up. But you said 'Let us find out all that Arthur Constant did in the last few months of his life.' Wimp couldn't miss stumbling on Jessie sooner or later. I'd have throttled Constant, if I had known he'd touched her," he wound up with irrelevant indignation.
Grodman winced at the idea that he himself had worked ad majorem gloriam of Wimp. And yet, had not Mrs. Wimp let out as much at the Christmas dinner?
"What's past is past," he said gruffly. "But if Tom Mortlake hangs, you go to Portland."
"How can I help Tom hanging?"
"Help the agitation as much as you can. Write letters under all sorts of names to all the papers. Get everybody you know to sign the great petition. Find out where Jessie Dymond is—the girl who holds the proof of Mortlake's innocence."
"You really believe him innocent?"
"Don't be satirical, Denzil. Haven't I taken the chair at all the meetings? Am I not the most copious correspondent of the Press?"
