Cleo F. Garis, The Mystery of Jockey Hollow
“ So Sycamore Hall, like many another old Colonial mansion, contained secret passages. The one from the wine bin to the smokehouse is quite simple. The other is more complicated. The closet has a false bottom. In it is a trapdoor so well fitted into the floor that one not in the secret would have difficulty in finding it. By pressing on a certain place in the wall, the trapdoor opens, a person can jump or slide down the chute, which is curved in such a way that no harm results from its use. ”
