One day in November, Dick returned to his home to discover that it had been burglarized, with his safe blown open and personal papers missing. The police were unable to determine the culprit, and even suspected Dick of having done it himself. Shortly afterward, he was invited to be guest of honor at the Vancouver Science Fiction Convention in February 1972. Within a day of arriving at the conference and giving his speech "The Android and the Human", he informed people that he had fallen in love with a woman named Janis whom he had met there and announced that he would be remaining in Vancouver. An attendee of the conference, Michael Walsh, movie critic for local newspaper "The Province", invited Dick to stay in his home, but asked him to leave two weeks later due to his erratic behavior. This was followed by Janis ending their relationship and moving away. On March 23, 1972, Dick attempted suicide by taking an overdose of the sedative potassium bromide. Subsequently, after deciding to seek help, Dick became a participant in X-Kalay (a Canadian Synanon-type recovery program), and was well enough by April to return to California.
