»La segunda cuestión consiste en el modo del descenso. Mi paseo con usted por la parte trasera de la casa me satisfizo al respecto. A unos cinco pies y medio de la ventana en cuestión corre una varilla de pararrayos. Desde esa varilla hubiera resultado imposible alcanzar la ventana, y mucho menos introducirse por ella. Observé, sin embargo, que las persianas del cuarto piso pertenecen a esa curiosa especie que los carpinteros parisienses denominan ferrades; es un tipo rara vez empleado en la actualidad, pero que se ve con frecuencia en casas muy viejas de Lyon y Bordeaux. Se las fabrica como una puerta ordinaria (de una sola hoja, y no de doble batiente), con la diferencia de que la parte inferior tiene celosías o tablillas que ofrecen excelente asidero para las manos. En este caso las persianas alcanzan un ancho de tres pies y medio. Cuando las vimos desde la parte posterior de la casa, ambas estaban entornadas, es decir, en ángulo recto con relación a la pared. Es probable que también los policías hayan examinado los fondos del edificio; pero, si así lo hicieron, miraron las ferrades en el ángulo indicado, sin darse cuenta de su gran anchura; por lo menos no la tomaron en cuenta. Sin duda, seguros de que por esa parte era imposible toda fuga, se limitaron a un examen muy sumario. Para mí, sin embargo, era claro que si se abría del todo la persiana correspondiente a la ventana situada sobre el lecho, su borde quedaría a unos dos pies de la varilla del pararrayos. También era evidente que, desplegando tanta agilidad como coraje, se podía llegar hasta la ventana trepando por la varilla. Estirándose hasta una distancia de dos pies y medio (ya que suponemos la persiana enteramente abierta), un ladrón habría podido sujetarse firmemente de las tablillas de la celosía. Abandonando entonces su sostén en la varilla, afirmando los pies en la pared y lanzándose vigorosamente hacia adelante habría podido hacer girar la persiana hasta que se cerrara; si suponemos que la ventana estaba abierta en este momento, habría logrado entrar así en la habitación.
“The next question is that of the mode of descent. Upon this point I had been satisfied in my walk with you around the building. About five feet and a half from the casement in question there runs a lightning-rod. From this rod it would have been impossible for any one to reach the window itself, to say nothing of entering it. I observed, however, that the shutters of the fourth story were of the peculiar kind called by Parisian carpenters ferrades—a kind rarely employed at the present day, but frequently seen upon very old mansions at Lyons and Bordeaux. They are in the form of an ordinary door (a single, not a folding door), except that the lower half is latticed or worked in open trellis—thus affording an excellent hold for the hands. In the present instance these shutters are fully three feet and a half broad. When we saw them from the rear of the house, they were both about half open—that is to say, they stood off at right angles from the wall. It is probable that the police, as well as myself, examined the back of the tenement; but, if so, in looking at these ferrades in the line of their breadth (as they must have done), they did not perceive this great breadth itself, or, at all events, failed to take it into due consideration. In fact, having once satisfied themselves that no egress could have been made in this quarter, they would naturally bestow here a very cursory examination. It was clear to me, however, that the shutter belonging to the window at the head of the bed, would, if swung fully back to the wall, reach to within two feet of the lightning-rod. It was also evident that, by exertion of a very unusual degree of activity and courage, an entrance into the window, from the rod, might have been thus effected. By reaching to the distance of two feet and a half (we now suppose the shutter open to its whole extent) a robber might have taken a firm grasp upon the trellis-work. Letting go, then, his hold upon the rod, placing his feet securely against the wall, and springing boldly from it, he might have swung the shutter so as to close it, and, if we imagine the window open at the time, might even have swung himself into the room.
