Emanuel (Manu) Rosen, the author of “If Anyone Calls, Tell Them I Died,” grew up in Israel and now lives in Menlo Park. It was not until he was a grown man that his mother informed him that her father, who came to Israel as a refugee from Nazi Germany, had committed suicide decades earlier. The cause of death had never been discussed.
