Whether Buddha spoke or not is doubtful.

Certain of the spectators thought that he said, 'Must a fagotnit', which is Hindustanee for "Blessings on this house." To Mrs.Rasselyer-Brown's distracted mind it seemed as if Buddha said, "I must have forgotten it" But this wild fancy she never breathed to a soul.
Silently Buddha recrossed the room, slowly wiping one arm across his mouth after the Hindu gesture of farewell.
For perhaps a full minute after the disappearance of Buddha not a soul moved.

Then quite suddenly Mrs.Rasselyer-Brown, unable to stand the tension any longer, pressed an electric switch and the whole room was flooded with light.
There sat the affrighted guests staring at one another with pale faces.
But, to the amazement and horror of all, the little table in the centre stood empty--not a single gem, not a fraction of the gold that had lain upon it was left.

All had disappeared.
The truth seemed to burst upon everyone at once.

There was no doubt of what had happened.
The gold and the jewels had been deastralized.
