Briefly, here is just what happened: Houdini had secured permission from Superintendent Pierce to make an effort to escape from the city prison, and this forenoon, in the presence of about 30 men, the superintendent let Houdini into cell No. 77 on the ground floor of the Tombs, where Houdini, in the presence of the witnesses of the test, removed every stitch of his clothing, which he left lying on the bunk in the cell. When he came out, Capt. Clarence A. Swan, the keeper of the prison, locked the cell door upon Houdini's clothing, and then the young man was taken to the second floor of the block of cells, where Superintendent Pierce and a number of the men witnessing the test searched his hair for possible concealed keys or other instruments. Not a thing was found, and Houdini even asked to have his feet examined so there would be no question of his having a key concealed between his toes, and this was done.

After that Houdini was locked in cell No. 60, and Superintendent Pierce and the witnesses went downstairs and out into the office, expecting Houdini would go there, providing he got out of his cell, and the police officials who were present seemed to feel pretty confident that he couldn't do that. This feeling was shared by some of the outsiders present, who could not bring themselves to believe that it could be done.

A few of the witnesses, however, went out into Somerset Street to wait and watch; for, knowing Houdini, they were prepared to see him come out anywhere.
