Parfitt, author of Operation Moses ( LJ 10/15/85), here writes a combined travel book and history of Jewish communities in Asia and Africa. With ``the lost tribes of Israel'' as theme, he explores such groups as the Makuya and the Beit Shalom in Japan, the Lemba in South Africa and Zimbabwe, and the Falashas in Ethiopia; analyzes the ethnic differences between the Baghdadi Jews and the Bene Israel of Bombay; and lays bare the conditions of the Jewish communities of Syria and Singapore. Some material, especially that about the Lemba and Japanese Judaic-like groups, is not easily accessible elsewhere. For large Judaic and religious collections. Maurice S. Tuchman, Hebrew Coll. Lib., Brookline, Mass.
