eleven
o'clock
We will let you know later in the day . '' Leaving Don Esteban , the boys started for the plaza , intending to play the part of sightseers and visit every place in which a mountebank might reasonably expect to go . They felt certain that Strong would keep away from the more aristocratic places . Keeping their eyes open and ever on the alert , they wandered about the streets and into many public places , but up to eleven o'clock had made no discovery . Then they entered a cantina for breakfast , purposely choosing one that was little frequented by Americans . Seating themselves at a table in one corner where they could see without being seen , the boys ordered a hearty breakfast and then turned their attention to the others in the place . At the table nearest them were three men of ordinary appearance , busy with their meal .
