Monday Mourning is the seventh novel by Kathy Reichs starring forensic anthropologist, Temperance Brennan.

Kathy Reichs herself is a forensic anthropologist who works for Office of the Chief Medical Examiner, State of North Carolina, and for the Laboratoire des Sciences Judiciaires et de Médecine Légale for the province of Quebec.

The plot of the story revolves around Brennan trying to decipher the clues left behind by the skeletons of three girls found in a pizza parlor basement in Montreal, Quebec, Canada, which has a colourful history.

Brennan's forensic expertise tells her that the people were buried after 1955, but homicide detective Luc Claudel is convinced the bones are pre-1955, and dismisses the case.

At the end of the book, Reichs writes that her inspiration for the plot was three skeletons she was sent to investigate that were found in a pizza parlor basement.
