Devil's Dice by William le Queux

In my own room I sat for a long time silent in deep reverie. Saunders glided in and out, brought me a brandy-and-soda that went flat, untasted, and placed at my elbow my letters, with a deferential suggestion that some of them might be important. Glancing at their superscriptions, I tossed them aside, in no mood to be bothered with cards of invitation or tradesmen's circulars.

Two hours passed, and the ever-watchful Saunders retired for the night. Then, after pacing the room for a long time in hesitation, I at last determined to write to Jack, who had returned home, warning him of his peril. I knew that by shielding a murderer from justice I accepted a great moral responsibility; nevertheless, I had formed a plan which I meant at any hazard to pursue. It was, I felt certain, my last chance of obtaining the knowledge I had so long and vainly sought, therefore I sat down, wrote a hurried note to him, in which I urged him to fly and hide himself for a time; but, after obtaining a hiding-place, to telegraph to me, using the name of a mutual friend, as I desired to see him at the earliest possible moment. This note I took across to the Club, and gave it to the commissionaire, with strict injunctions to deliver it personally.
