A Grave Breach

In Macomber's unremarkable third legal thriller to feature John Cann (after 2003's Art & Part), Cann, a lawyer at a prominent white-shoe Washington, D.C., firm with links to the CIA, reluctantly agrees to represent Dubran Mribic, a suspected Bosnian Serb war criminal, being held by the German authorities. Cann dislikes being put in a position where he knows his client is guilty. Mribic has links with an old massacre with a personal connection to Arthur Matsen, the founder of Cann's firm. An unrelated subplot mostly occupies the requisite beautiful and brainy sidekick. Thriller fans will likely find Cann's transformation from desk attorney to action hero unconvincing.
