The two quickly became lovers and met clandestinely at Sanhuber's boarding room or at a nearby hotel. They also arranged trysts at Dolly's home but, when neighbors began noting Otto's increasingly frequent comings and goings, and alerted her husband, Dolly suggested to Otto that he quit his job and secretly move into the Oesterreichs' upstairs attic to allay any further suspicions. He readily agreed to the arrangement.
