Irish Gilt: A Mystery Set at the University of Notre Dame

In McInerney's ninth Notre Dame mystery (after 2004's Green Thumb ), professor Roger Knight and his detective brother, Philip, seek the missing diaries of Fr. John Zahn, an almost forgotten 19th-century theologian, which purport to shed light on the search for El Dorado. Their investigation takes a deadly turn after the murder of an alumnus on campus. Rare book dealers, academic curmudgeons and others with conflicting loyalties and assorted agendas enliven a sleuthing exercise short on suspense and imagination. (Oct.)
