at first, but gradually growing blacker and spreading until finally it hung like a huge drop-curtain screening the stars. The street lay in darkness. From a window in the top of the arch a single light was visible, pale and flickering as the ray from a candle; otherwise the grey bulk of the building seemed lost in the shadows, lifeless and silent. Suddenly the light went out. "Hist—st!" As if at a signal something moved on the staircase, creeping forward, and then from the shadow of the tenement, from under the archway, emerged other shadows, moving slowly like wraiths, hesitating, stopping, losing themselves in the general blackness, and then stirring again; shadows within shadows creeping. Presently a door at the top of the steps opened and shut. Every time it opened, a shadow passed through and another crept forward.

By the light of the candles the shadows now took shape, the one from the other, and twelve black-cloaked and hooded figures stole forward, also masked to the lips. They passed one by one before the seated mask, touching his hand lightly, fleetingly, as one dipping the fingers into holy water, and then around the table to their seats, each in turn, until all
