Have Mercy on Us All

The chief attraction of Fred Vargas’s novels is her cast of characters, led by Chief Inspector Adamsberg, a most unconventional leader of any criminal investigation outfit. Small and disheveled, good with animals and children, dreamy and often seemingly idle, Adamsberg is not only extremely bright but has confidently surrounded himself with remarkable colleagues. Hard-drinking Adrien Danglard, a single father of five with a huge store of ready information, and Violette Retancourt, a woman of prodigious strength and courage, are among his entertaining subordinates, along with Snowball, the division’s cat that proves equally remarkable in one memorable outing.
