The Sinner
by Tess Gerritsen
When two Boston nuns are found brutally beaten--one fatally and one with a scintilla of life left in her--it's up to homicide detective Jane Rizzoli to find the perpetrator. Medical examiner Dr. Maura Isles, nicknamed the Queen of the Dead, has the unlucky fortune to discover that the murdered nun, a young woman about to make her final vows, hid untold secrets from the rest of the aging convent. Both fallen Catholics, Rizzoli and Isles seek to reconcile the viciousness of the crimes with the seeming blind faith of the victims. Another dead body turns up, and the investigators must rely on their clinical analysis, lest they be sucked in to the drama unfolding before them. Each woman immerses herself in her work rather than face the outside world; Rizzoli refuses to face the truth of what her future holds, and Isles denies her own loneliness.
