Literal
She [topic-は] deserter [object-を] harbored.
かくまう ('to shelter, harbor, hide a fugitive') is a vivid verb that pretty much always carries criminal or wartime overtones — sheltering someone whose presence ought to be reported. 脱走兵 ('deserter,' lit. 'flee-run soldier') is a wartime/military compound. The combination evokes a clandestine wartime scene; the verb itself is rare enough in everyday speech that encountering it usually flags fiction or news.
