"Leo sighed and went back to her work, but by the time she re..." — Holly Green quote meaning

Leo sighed and went back to her work, but by the time she reached her little apartment on the houseboat moored to Gezira Island she was weary and on edge. She could not get the thought of Alix caught up in a battle out of her head. Sasha’s informant had described how she had been honoured by Tito for her role as a bombasi, hurling grenades into enemy bunkers. It wasn’t hard to imagine how dangerous that would be. She longed to confide in someone, to share her anxiety, but there was no one she could tell without divulging her source. She considered trying to get a phone call through to Sasha in London but dismissed the idea. It was unfair to burden him with the same worry when he was as helpless as she was. Apart from that, she was not sure how he would react. He hated the idea of women anywhere near the front line, as she knew from her own experience. In addition, Alix was fighting on the wrong side as far as he was concerned.
