midnight
She was not so sure as Julie of Thorpe 's innocence , but she meant to find another suspect if one could be found , and she redoubled her efforts . Zizi had become a welcome guest in the Thorpe household , and they all admired and loved her . A most adaptable little piece , she fitted into the family as if she belonged there , and she and Julie were warm friends . She said nothing of the midnight intruder , being determined in her own mind , that he was an emissary from the medium , Madame Parlato , whom Zizi regarded as an absolute fake . To prove this was a desire of Zizi 's mind as well as to solve the mystery of the Blair murder . But her fondness for the Cranes was such , that she was not sure she should expose the medium 's trickery , even if she discovered it herself . So she went on with her secret investigations , and at present they included an inquiry into the matter of that reporter 's visit and John Harrison 's appearance on the scene .
