"Peter, I believe those scoundrels are up to their old game, and that we are watched. Once or twice since we have been sitting here I have noticed a heavy-looking fellow glance at us very closely as he passed, and I just saw the same fellow, who was evidently hiding from observation, nod to that girl, and beckon her away."

"Her story was a lie from beginning to end," Peter said, "and it is quite possible that it was a got-up thing, on purpose to see whether we could talk Spanish well. I don't think any one could swear to us who only saw us then; but the fact of our speaking Spanish so well would go a long way towards settling the point in the mind of any one who suspected us!"

"We must be careful in future, Peter, and avoid quiet streets after dark, and keep a sharp look-out at all times, or we shall get a knife between our ribs, as sure as fate."

Time, however, passed on without anything occurring to give any support to their suspicion, they could not discover that they were being watched, or their footsteps dogged. They, nevertheless, continued to be, to a certain extent, upon their guard after dark; in the daytime the number of English soldiers about the streets was so large that there was very little danger of any attack.
