“I was not referring only to what Stephen has told us, although that was, as you say, very interesting. While he was talking I was looking about the room, and I have seen a very strange thing. Let me show it to you.”

He linked his arm in mine and, walking me back into the room, halted opposite the fireplace.

“There,” said he, “look at that. It is a most remarkable object.”

I followed the direction of his gaze and saw an oblong frame enclosing a large photograph of an inscription in the weird and cabalistic arrowhead character. I looked at it in silence for some seconds and then, somewhat disappointed, remarked:

“I don’t see anything very remarkable in it, under the circumstances. In any ordinary room it would be, I admit; but Stephen has just told us that his uncle was something of an expert in cuneiform writing.”

“Exactly,” said Thorndyke. “That is my point. That is what makes it so remarkable.”
