The elderly Beagle sisters continue to operate their late brother's private detective agency in New York City. Their second and final case finds the two looking into the murder of a society girl strangled with a diamond necklace. Originally published in 1941.
Narrated by cousin Martha Meecham, this is the second of the Beagle Sisters (Amanda and Lutie) mystery stories. The Beagles were hired to protect some jewelry that was being displayed at a posh party only one of the debs wearing a million dollar necklace is dead. While most of her friends and family believe the victim, Hero, to have committed suicide by catching the necklace on the back of a chair and then strangling herself, younger sister Lutie astutely notes the signs that it had to be murder. When the girl's stepmother is also murdered, the stakes go up considerably as it seems this murderer doesn't mind eliminating anyone who gets in teh way. There are a satisfying number of red herrings and the conclusion is also wonderful. I didn't read the first book in the series and was able to follow just fine.
Beagle Detective Agency is hired to provide guards for a jeweler's party, and Lutie persuades her sister Amanda that they should be in attendance as well. When there's a high society death, it's Lutie's sharp eye that convinces the police it's not a suicide. Cousin Marthy tells the story, down to Lutie's narrow escape from a murderer, in this delightful period piece.
