But he accomplished it.

Having gained access to one of the shops in another part of the building, he at once turned his attention to the vaults.

Once these had connected from one end of the building to the other.

Some of the arched communicating doorways had been closed up by wooden barriers.

These Shadow found means to get the better of, and passing through, would replace the boards he loosened, so that they bore no signs of having been tampered with.

At last he gained access to the vault beneath the portion of the building used as a "fence."

It was not a hard job now for him to get up-stairs.

He had only to wait his chance, and then quietly slide up the stairs communicating with the store-room above.

Once this was performed without being observed, he found no difficulty in concealing himself in the piles of old junk and goods of all descriptions with which the place was filled.

There were times when the place was left without a single occupant.
