I picked up the first four books in Winston Churchill's "The Second World War" from a local thrift store. I believe that the set is incomplete because the original owner went to Korea and did not return. I would like to research this person and confirm it deny my suspicions. How do I go about this?
Their church would likely have records of their death, if their remains were sent home they'd be buried in the churchyard. Someone might have done the work for you, if you put their name into one of the various genealogical services it may come up. Barring that, your local library should have collections of historical newspapers, losing a member of your community in the war would be recorded there.
