Nothing spells comfort like an old-school British mystery. It just so happens that the Nichols Library has two new ones to offer. “ Journey to Munich” by Jaqueline Winspear (print and CD) sends Masie Dobbs on mission into Nazi Germany to free a political prisoner. In “Treachery at Lancaster Gate,” by Anne Perry, a bomb goes off in London during a secret police raid, claiming several lives. Commander Thomas Pitt suspects the blast was a calculated cover-up of murder. “The Death of Mary Russell” by Laurie King, Sherlock Holme’s housekeeper Mrs. Hudson returns home to find Mary Russell missing and signs of foul play.
