“I am looking for a broken tumbler or wine-glass. It is a thin glass vessel decorated with a pattern of small, eight pointed stars. It may be in the dust-bin or it may be inside the house.”
The inspector hesitated, but Thorndyke’s confident manner had evidently impressed him.
“We can soon see what is in the dust-bin,” he said, “though what in creation a broken tumbler has to do with the case is more than I can understand. However, here goes.” He sprang up onto the wall, and, as he dropped down into the garden, the station-master and I followed.
Thorndyke lingered a few moments by the gate examining the ground, while the two officials hurried up the path. Finding nothing of interest, however, he walked towards the house, looking keenly about him as he went; but we were hardly half-way up the path when we heard the voice of the inspector calling excitedly.
“Here you are, sir, this way,” he sang out, and, as we hurried forward, we suddenly came on the two officials standing over a small rubbish-heap and looking the picture of astonishment. The glare of their lanterns illuminated the heap, and showed us the scattered fragments of a thin glass, star-pattern tumbler.
“I can’t imagine how you guessed it was here, sir,” said the inspector, with a new-born respect in his tone, “nor what you’re going to do with it now you have found it.”
“It is merely another link in the chain of evidence,” said Thorndyke, taking a pair of forceps from the case and stooping over the heap. “Perhaps we shall find something else.” He picked up several small fragments of glass, looked at them closely and dropped them again. Suddenly his eye caught a small splinter at the base of the heap. Seizing it with the forceps, he held it close to his eye in the strong lamplight, and, taking out his lens, examined it with minute attention. “Yes,” he said at length, “this is what I was looking for. Let me have those two cards, Jervis.”
I produced the two visiting-cards with the reconstructed lenses stuck to them, and, laying them on the lid of the case, threw the light of the lantern on them. Thorndyke looked at them intently for some time, and from them to the fragment that he held. Then, turning to the inspector, he said: “You saw me pick up this splinter of glass?”
“Yes, sir,” replied the officer.
“And you saw where we found these spectacle-glasses and know whose they were?”
