It must have fallen again, for the voice 'came a third time--"'Ware window!" And on this occasion the archer was successful, guided doubtless by the illumination of the lantern the guard had hung on a nail, and whose flicker would outline the lattice faintly against the darkness of the wall.
An arrow entered with a soft hiss.

It struck beyond them with a click, and its iron point tinkled on the floor, the plaster of the opposite wall not holding it.
Sholto scrambled about the floor on hands and knees till he found it.
It was a common archer's arrow.

A cord was fastened about it, and a note stuck in the slit along with the feather.
"It is my brother Laurence," whispered Sholto.

"I warrant he is beneath with a rope and a posse of stout fellows.

We shall escape them yet." But even as he raised the letter to read it by the faint blue flicker of the lantern, there came a cry of pain from within the castle.
