Part 7 (1/2)

'He said that she wore a coat with a deep cape, and that she rested one arm upon the case.'

'Well, I did wonder what the woman's dress had to do with it. 'Gad, but you questioned those people until I began to feel sorry for them.

What figure, now, is the dress likely to cut?'

I laughed.

'In this case let us suppose that the young woman is one of the gang.'

'Oh!'

'And let us fancy that while she peered at the pink topaz--you remember Lausch told us that she excused her nearness by saying that she was very near-sighted?'

'That's so.'

'Well, while looking at the gems, with her face bent over the case, one arm upon the edge, and with the voluminous cape outspread, what is to prevent her using the other hand and arm to draw a diamond point slowly and heavily along the gla.s.s, close to the metal?'

'By Jove! what indeed?'

'And why may not this act be repeated, three or four times, say, by the same woman, slightly changed as to dress, as she could have been?

Lausch, you recall, accosted her.'

'Yes.'

When Dave grew laconic I knew him to be almost convinced.

'You will recall how each of the attendants remembered one or more instances of persons lingering long near the gems, or crowding so close as to attract the attention of some of them.'

'Umph!'

'And Lausch distinctly remembered how a good-natured guard came to his aid just as he was about to close his exhibits, and stood with his back to the case, and his arms carelessly outspread upon the edge chaffing with a group of late sight-seers, and keeping them from annoying him (Lausch) while he made things secure. Now I don't say that it was done, but I can see how that guard might have played into the hands of the gang, who might have been at hand three or four strong. Observe, the cases were high at the inner sides and shallow at the front, and while the top sheet of gla.s.s, for purposes of display, was a large one, those forming the outer side were small and set into stout bronzed squares not to exceed seven inches in depth and ten in length. Now, we will note that the back of the case, besides being higher than the front, is not of gla.s.s, but of wood, to admit of the use of a mirror for lining, and to double the show and glitter of the gems.'

'Upon--my--word!'

'Now let us suppose our guard as standing before the case and directly in front of the diamonds. He is facing outward, and before him, hovering close, are some others, two or three, or more. On the other sides of the octagonal pavilion the other a.s.sistants are busy ”closing up.” Lausch in person presides at the small safe in the centre of the place. Now, while he is busy, with his eyes averted for a moment, a hand thrust under the outstretched arm of the guard may gently press something adhesive against the already cut gla.s.s and pull it out, and soon, when Lausch bends down to open the safe, or to place some article therein, the hand draws out the little tray of gems; it was small, and could have been concealed under one of those wraps thrown conveniently across the arm. Now, a little ruse to subst.i.tute the false gems and replace the gla.s.s under the guard's concealing arm, and the thing is done. If it all happened at the closing hour, when the big building was shadowy and one could see clearly only a short distance, when every exhibitor was occupied with his own, and visitors, for the most part, were intent upon reaching the nearest exit--it was bound to succeed. Of course this is all theory, but----'

'It's the explanation of that theft, or I'm a sinner!' cried Dave, jumping up and beginning to pace the floor nervously. 'Carl, old man, I'll never chaff your ”b.u.mp of imagination,” after to-day. I'm ready to begin work on just that theory.'

'Steady, steady, Dave.'

'All right, sir; at least we can make a beginning--we can find that guard.'

'How?'

'Take his description from Lausch--find out who was detailed here----'

I put up my hand, and he stopped--staring.

'Dave, there is not a Columbian guard on the force who would, or could, have played that part--if it was played. It was simply one of the band wearing a guard's uniform.'
