They waited until after eleven o'clock before they left the corner of Second and Spring in the mayor's car. It was Saturday night and there were twice as many people on the streets at that hour than during the week days. As their paper published no Sunday edition, John and Brennan realized that if they were successful the exposure of the Gibson-Cummings' plot could not be made until Monday or Tuesday at the earliest, which would be three or four days before the primary election, scheduled for Thursday.
At Brennan's order the mayor drove the automobile up and down Spring street, from Second to Eighth and back. Each trip as they passed the saloon they watched for signs of it being closed for the night. At half-past eleven they saw that the lights were extinguished, the doors closed and the steel lattice work drawn across the open front to protect the cigar stand for the night.
The mayor swung the automobile into the first street intersecting Spring street, toward Main, stopping it at Brennan's instructions so that it could be driven into the alley without difficulty. Brennan, Smith, Murphy and John left the machine and hurried into the alley. Murphy carried a brace and bit hidden under his coat. John's left arm was stiff at his side from a steel bar thrust up into the sleeve and Brennan carried the dictograph in a paper package under his arm.
Holding close to the shadows of the brick wall, they walked rapidly to the basement door, opening it and entering quickly. Murphy and Smith were posted at the door to act as guard and to watch for the arrival of Gibson and Cummings. Brennan and John went directly to the trap door at the top of the stairs at the front of the basement. Brennan pushed upward against the door, but it held fast against his strength. John handed him the steel bar. A thrust, a wrench, a tearing of decayed wood and the door yielded. They scrambled through to the floor of the saloon, finding themselves within a few feet of the room where they were to "plant" the dictograph.
"Luck is with us this time," said Brennan as they saw that the door of the room was open. He knelt in the open space between the tiers of drawers on either side of the desk that filled one side of the room. In half a minute the brace was boring into the wood of the flooring. Through the hole cut through the floor Brennan pushed the wires of the dictograph until their entire length disappeared into the basement and the "ear" of the eavesdropping device was flat over the perforation. He swept up the shavings from the boring of the hole with his hands as they hurried back down into the basement, where they found the end of the wire dangling from the ceiling. Brennan assembled the dictograph rapidly, attaching to it three head-pieces with receivers clamping over the ears.
"We'll test it," he said to John. "Scoot upstairs and say something in a natural tone in all parts of the room. Try to talk at about the pitch you believe they will speak and drop your voice to a whisper occasionally. Ben and I will listen."
While Brennan and Smith waited with the headgears John followed orders, returning to the basement when he believed he had talked to himself long enough to make the test accurate.
"Works perfectly," Brennan told him.
"Heard every word you said. We're all set and ready to go."
John glanced at his watch. It was five minutes after twelve. They made themselves as comfortable as possible on the empty packing boxes. Smith produced his notebooks and a handful of carefully sharpened pencils.
