From the spectacles I turned to the pieces of reed. These were what had given Thorndyke his start. Would they give me a leading hint too? I looked at them and wondered what it was that they had told Thorndyke. The little fragment of the red paper label had a dark-brown or thin black border ornamented with a fret-pattern, and on it I detected a couple of tiny points of gold like the dust from leaf-gilding. But I learned nothing from that. Then the shorter piece of reed was artificially hollowed to fit on the longer piece. Apparently it formed a protective sheath or cap. But what did it protect? Presumably a point or edge of some kind. Could this be a pocketknife of any sort, such as a small stencil-knife? No; the material was too fragile for a knife-handle. It could not be an etching-needle for the same reason; and it was not a surgical appliance⁠—at least it was not like any surgical instrument that was known to me.
