Escape
Gradually a greater amount of liberty was given to Gervaise. Escape from Tripoli was deemed impossible, especially as he was supposed to be entirely ignorant of Arabic. He was, indeed, scarcely regarded now as a slave by the head mason, and instead of being clad in rags was dressed like other overseers. He was no longer obliged to walk with the gang to and from the palace, and was at last granted permission to go into the town for an hour or two after his work was over, instead of returning direct to the prison. The first time this permission was given to him he placed himself on the road by which Ben Ibyn would leave the town, choosing a quiet spot where the meeting would not be observed. Gervaise had for some time taken to staining his face, hands, and legs with walnut juice, beginning with a weak solution, and very gradually increasing the strength until he had reached a shade approximating to that of the lighter coloured portion of the population. The head mason had on one occasion noticed it, and said, "The sun is darkening your skin, Gervaise, until you might verily pass as a Moor."
