As we Forgive Them by William le Queux

The fine old church, with its heavy gildings, its tawdry altars and its magnificent frescoes, was in such gloom that at first, on entering from the street, I could distinguish nothing plainly, but as soon as my eyes became accustomed to the light I saw within a few yards of me a countenance that was distinctly familiar, a face that caused me to pause in anxious breathlessness.

Standing there, behind those scattered kneeling women, with the faint, flickering light of the altar candles illuminating his face just sufficiently, the man's head was bowed in reverence and yet his dark, beady eyes seemed darting everywhere. By his features -- those hard, rather sinister features and greyish scraggy beard that I had once before seen -- I knew that he was the man who had made the secret appointment with Burton Blair, yet, contrary to my expectations, he was attired in the rough brown habit and rope girdle of a Capuchin lay brother, a silent, mournful figure as he stood with folded arms while the priest in his gorgeous vestments mumbled the prayers.
