"Whew! you're aiming high, I must say, old chap. If not a human being, what sort of a creature could the clever thief be? I've heard of monkeys stealing things and hiding the same away in a spirit of covetousness; but then the old lady doesn't happen to have a simian for a household pet, that I know of." "No, but she has got a poll-parrot, as I told you, Thad!" observed Hugh, calmly. "Oh! do you suspect that a silly bird could go and carry off not only one spoon but three of them?" gasped the other boy. "What would a parrot want of such objects, and where would she hide them?" "Remember, this is only guess work on my part, because, so far, I haven't any positive evidence that it's so. But I remembered once reading an article about some birds having a weakness that way. Generally it was a raven that did it, and hidden away in a dark corner they would find trinkets and spoons and all sorts of things that were of no possible use to any bird. In every instance they seemed to be bright and tempting, as if the bird had no eye for dingy things. Well, these spoons have recently been scoured and cleaned so that they shine splendidly!" "Oh! now that you mention it, Hugh," broke out Thad, "I remember that several years ago, before I knew you, with another boy I climbed a tall tree to peek in at the nest of a pair of crows. Well, sir, besides the young ones, what did we find but three strange things. One was a key, pretty rusty at that; another seemed to be a piece of metal that might have fallen off a motor car on the road; it was made of brass, and still shone fairly well. The third I've forgotten about, though I've still got them all at home somewhere. At the time, Dick Saunders and I laughed, and said the old mother crow had fetched her babies some playthings to keep them amused while she and her mate were off hunting grubs and corn and such crow food." "Well, all of which goes to prove that my little theory mightn't be so far fetched as you seemed to think in the beginning," said Hugh. "I mean to look around closely the next time I drop in to see the Madame. Perhaps if I picked up a tiny green feather that must have come from Pretty Poll, and on the table close to the case that holds the spoons, it might clinch matters." "Whew! I only hope you do!" declared Thad. "I'd hate to learn that Owen had any hand in taking those spoons. The sooner we find out the truth, the better for all concerned. It'll not only relieve our minds, as well as that of the old lady; but either prove or disprove the suspicions we're right now entertaining toward that poor boy." He looked very determined when saying this, just as though he had made up his own mind to hasten the denouement; but of that he did not say anything to Hugh.
