Whodunit? It doesn’t matter anymore.

Crime novelist Patricia Cornwell has settled a lawsuit against her former business managers, avoiding a second trial for a case that dates to 2009, the two sides announced Tuesday.

The author had claimed the New York accounting firm Anchin, Block & Anchin LLP was negligent in handling her finances and cost her millions in losses or unaccounted-for revenue. A federal jury awarded the author $51 million in 2013, but a judge reversed the decision.

An appeals court last year granted Cornwell a new trial. The case was dismissed Tuesday after the sides reached a settlement.

Cornwell is best known for her series of novels featuring medical examiner Kay Scarpetta.

Cornwell’s attorney, Joan Lukey, released the following statement: “Patricia Cornwell and her former business managers, Anchin, Block & Anchin LLP and Evan Snapper, announced today that they have amicably resolved their disputes and will be dismissing the pending litigation in Boston.’’

An Anchin spokesman could not immediately be reached.
