Murder In the North End — P.B. Ryan

July 1870. Amidst the splendor and opulence of the Gilded Age, Nell Sweeney enjoys a different kind of wealth as governess for the Hewitts of Boston. Her employment has been a privilege in an era of severe class distinctions. But her contact with high society sometimes reminds Nell that despite her lofty position, many will regard her as no better than the thieves and killers who happen to share her Irish heritage...

Colin Cook was the only officer in the city's Detective Bureau not to be found guilty of corruption and to escape being demoted or fired. But now he is a fugitive, wanted for killing a petty criminal in Boston's North End, and the police believe Nell knows where the Irish cop is hiding.

Nell doesn't know where Colin is, nor does she believe her friend is capable of murder. To prove his innocence, she descends into the seedy and dangerous slums of the North End to look into the matter. Nell isn't afraid of her fellow immigrants in the neighborhood, but Dr. Will Hewitt has his doubts--and he won't let her conduct this investigation alone...
