Just in time for the holidays, New York Times bestselling author Sheila Connolly gives you a short story that will whet your appetite and last just as long as your tea stays warm.In this quick taste of Sheilas mysteries, a neighborhood that takes care of their own sometimes has to take care of business . . .Dintys Bar has occupied the same corner in Cambridge since before I was born. Not the Cambridge with the glitzy shops and exotic restaurants catering to parents dropping their little darlings off at the Big H, or the Cambridge filled with techy wonks. Dintys keeps a toehold in the back end of Cambridge, between Central Square and the river. Its patrons come from the neighborhood and theyre pretty consistent blue-collar, mostly construction workers, a scattering of cops and firefighters, all Irish in some way or another.
