Jimgrim by Talbot Mundy

There was a sensation -- tension -- as we three strode toward the centre of the room. The face had vanished, leaving behind the same sort of effect that a monster might produce by peering, head and shoulders, from a pond and then submerging. There were the ripples. What was it? The dancing-girls were awestruck and as suddenly quiet as birds that have seen the shadow of a hawk -- until the music resumed, and then one of them laughed and they all joined in, not knowing why. That gave us opportunity to speak. Chullunder Ghose tried to control his voice, but it came in a scared whisper, and there was sweat on his jowls:

"Rammy sahib, have you seen the garden? There is something there that the girls think is Indra's chariot. They are forbidden to look, so they have all peeped. They are forbidden to speak of it, so they told me."
