<p>The University of Notre Dame relies on Roger Knight, the rotund professor of Catholic Studies, and his brother Philip, a semiretired PI, to investigate certain delicate situations that could put the school in a bad light. Students, faculty, and alumni, like David Williams, are all fair game.<br><br>Having been a successful financial adviser until recently, David has returned to campus to renege on a pledged donation to the university's ethics program. While he's there, one of his former classmates sends a letter confessing to the murder and a secret burial of one of their closest friends, a student who had gone missing decades before and was never found. As students, David, Patrick, and Timothy made up the "Trinity," an irreverent nickname for three close friends and fierce rivals---be it for on-campus prestige or the affections of a beautiful St. Mary's student from across the road.<br><br>Ready to help the school put the whole sordid tragedy behind them, Roger and Philip set about the sad task of unearthing Timothy's body, only to find that they have a much bigger mystery with which to contend.<br><br>With rivalries rekindled and the brothers Knight digging into the university's past, <i>Sham Rock</i>, the latest in Ralph McInerny's well-loved mystery series, is as witty and charming as ever</p>
