A lost heir, murder most foul, and the unexpected return of two old friends start Mary Russell and Sherlock Holmes--spouses and intellectual equals--on an investigation that takes them from the trenches of World War I France to the heights of English society. In this sixth entry in Laurie King's award-winning series, fans will find the Baker Street sleuth mellowed by age and marriage yet still in possession of his deductive abilities and acerbic wit, and, in Mary Russell, a surprisingly apt companion for the legendary detective.

Justice Hall brings back two colorful characters from earlier in the series: Bedouins Ali and Mahmoud Hazr (now known as Alistair and Marsh), who last appeared in O Jerusalem. At their request, Holmes and Russell take up the trail of the doomed heir to Justice Hall, who has been executed for cowardice in the bloody trenches of France. As the detectives strive to make sense of his death and to locate another heir to the family title, an attempt is made on the life of the man who's soon to be welcomed as the new duke. Holmes and Russell soon realize something sinister is afoot, and that they must untangle a web of deceit to discover which of the many suspects is taking steps to shorten the line of inheritance. Once again, King's satisfying tale stays true to the spirit of Conan Doyle's original stories while extending them into new terrain. --Benjamin Reese
