Die Again, Mr. Holmes

A young woman begs Sherlock Holmes to help find her missing fiancé, but the great detective makes an uncharacteristic mistake. Then Sherlock's daughter, Lucy James, takes on a missing person case of her own.
But Lucy must also keep a vicious criminal away from Becky, Lucy's ten-year-old sister-in-law, and little Becky soon becomes dangerously involved in both cases.
No one foresees the devastating news that Sherlock Holmes has been murdered.
The newest adventure in this popular mystery series takes us from the Old Bailey courthouse and the seacoast lairs of smugglers to a grand British country estate and the posh financial headquarters of Lloyd's of London. For Watson, Sherlock and Lucy, survival will require valor, sacrifice, and acts that go far, far outside the law.
