“Would it not be well for us to reach the tomb before them, examine it thoroughly, and be on the eve of leaving at their arrival?” asked the Governor, of Julio.

“Our best policy, I believe, is to follow them at a slow pace, and be alighting from the cab as they enter the tomb. The law is on our side, and if we so desire, the arrest can be made inside the historic tomb,” replied Julio Murillo.

“We will not be connected outwardly with the arrest. On coming out of the tomb the police must know that the time to make the arrest has arrived,” replied the Governor.

“Here is the Mexican Annex, gentlemen,” said Julio Murillo, looking out of the window, “and our disguised friends are coming. They are more than a block away yet. We will move a block to the side to avert suspicion, from which point we can see them quite as well.”

The cab moved slowly and noiselessly away and soon disappeared amongst a hundred or more.

The great hotel was filled to overflowing, and the big crowd of fashionably-dressed people surged back and forth through the entrances.

Julio’s trained eye scanned every face, and now and then he uttered low exclamations of surprise. His two companions asked no questions, but arose from their seat and remained standing by his side, that they too might see what was going on around them.

“Ah, there is J. Ecarg, and Niksab, and Mr. and Mrs. Grange, out on a dress parade. I wonder if they are staying in the Mexican Annex now, or are they just hanging around trying to impress strangers with their importance,” said the Governor.

“Partly yes, and partly no,” said Julio. “Mrs. Grange has convinced herself by this time that she does not remember, and has met these men by appointment, which of course her husband made with them, not to arouse their suspicions. For had they known that it was Mrs. Grange who wished to see them, to interview them on ‘Memory Fluid,’ they never would have met.”

“See how she tosses her head and smiles at Mr. Niksab. She has probably heard of his good fortune and hopes to be presented with another costly frock,” said Señor Guillermo Gonzales. “Strange how susceptible some men are to such women’s charms.”
