Leo Leander was the occupant of the cab who saw they were being followed, and knew intuitively that trouble would result unless some way out of it could be invented quickly. “Gentlemen,” the aggressive señorita in disguise said, “gentlemen, I took the liberty to add another to our party to visit the ancient tomb—a gentleman by birth, a gentleman by education and social environments; a student and writer on anthropology, and a devotee to archæology. Friends, it is he you see, the Rev. Isaac Tombstone, Señor Enrique Arellano, and Don Jose M. Martinez.” It was quite evident from the expression on the faces of the pretenders introduced to Rev. Isaac Tombstone, that they would rather he were not one of their party. Leo Leander saw this, and very quickly remarked: “Brother Tombstone is better informed than any other man alive on prehistoric Mexico; on the written and unwritten history of Mexico up to the nineteenth century; and from that time on he has been an eye-witness to everything that has taken place upon the soil known as Mexico in the nineteenth century, and he fully sympathizes with the descendants of the Latin race who lost their country, their time-honored customs and religious stronghold. Gentlemen, the Reverend Tombstone is true to principle; rely upon him. He will fight to the finish to help down the present _régime_.” The assertion that the Rev. Isaac Tombstone had lived through two hundred years, and now sat before them a well preserved man, apparently not over sixty years old, in full possession of all his senses, was the only thing in the statements of Leo Leander which seemed incredulous to the listeners. However, they congratulated the Reverend Tombstone on being so hale and hearty at his great age and said they were delighted that he had joined their party, and hoped in the near future that they would become staunch friends. Leo Leander was delighted at the effect his words had created, and smiled serenely to himself as he watched the maneuvers of the Governor’s cab. He was leading them a lively chase. So lively, in fact, that the motorman of the Governor’s cab often was undecided just which way to turn. “We are discovered,” said Julio; “the aggressive señorita knows she is being followed, and it will take more than the quick eye of a hawk to keep her from eluding the law.” “Her cab certainly is not capable of swifter movement than ours,” said the Governor. “I do not think it possible for them to escape us.” “We will not lose sight of the cab entirely,” said Julio, “yet it is likely to lose one of its occupants on the way without our knowledge.” Señor Guillermo Gonzales did not make any comment, but gazed with much interest upon the remarkable panorama before him. “We certainly are not going directly to the city of the dead,” said the Governor.
