"There's something here that looks like a bone, sir," he sang out.
"Don't grub about, then," said the inspector. "Drive your shovel right into the mud where you saw it and bring it to the sieve."
The man followed out these instructions, and as he came shorewards with a great pile of the slimy mud on his shovel we all converged on the sieve, which the inspector took up and held over the tub, directing the constable and labourer to "lend a hand," meaning thereby that they were to crowd round the tub and exclude me as completely as possible. This, in fact, they did very effectively with his assistance, for, when the shovelful of mud had been deposited on the sieve, the four men leaned over it and so nearly hid it from view that it was only by craning over, first on one side and then on the other, that I was able to catch an occasional glimpse of it and to observe it gradually melting away as the sieve, immersed in the water, was shaken to and fro.
Presently the inspector raised the sieve from the water and stooped over it more closely to examine its contents. Apparently the examination yielded no very conclusive results, for it was accompanied by a series of rather dubious grunts.
At length the officer stood up, and turning to me with a genial but foxy smile, held out the sieve for my inspection.
"Like to see what we have found, Doctor?" said he.
I thanked him and stooped over the sieve. It contained the sort of litter of twigs, skeleton leaves, weed, pond-snails, dead shells, and fresh-water mussels that one would expect to strain out from the mud of an ancient pond; but in addition to these there were three small bones which at the first glance gave me quite a start until I saw what they were.
The inspector looked at me inquiringly. "H'm?" said he.
"Yes," I replied. "Very interesting."
"Those will be human bones, I fancy; h'm?"
"I should say so, undoubtedly," I answered.
"Now," said the inspector, "could you say, off-hand, which finger those bones belong to?"
I smothered a grin (for I had been expecting this question), and answered: "I can say off-hand that they don't belong to any finger. They are the bones of the left great toe."
The inspector's jaw dropped. "The deuce they are!" he muttered. "H'm. I thought they looked a bit stout."
"I expect," said I, "that if you go through the mud close to where this came from you'll find the rest of the foot."
The plain-clothes man proceeded at once to act on my suggestion, taking the sieve with him to save time. And sure enough, after filling it twice with the mud from the bottom of the pool, the entire skeleton of the foot was brought to light.
