At one of the last visits - possibly the final visit - Kay received from the Nazi security services, an arrest warrant ordering her transfer to the women's concentration camp at was brought for her. However, she was not present when the responsible official arrived to deliver the document: It is not clear whether she would have faced immediate arrest if she had been there. Either way, because of the requirement that the warrant be delivered "in person", it was not executed either then nor, thanks to the gathering chaos that descended on administrative structures in Germany during the final months of the war, subsequently. Relatively few details survive as to of how Kay lived during those years, but "casual meetings in small groups" at which one of the friends could pass on information discovered by listening (illegally) to foreign radio stations meant that she was not totally unaware of the unfolding of the war and other internationally reported events. The collapse of the National Socialist régime in May 1945 did not, therefore, come as a complete surprise to Kay.
