This just wasn't good, had nothing enjoyable about it I've read three books by her and only one, I kinda liked. Think I have to stop trying. Carolyn Wells mysteries is just not for me

Robert Pembroke has been found dead in a locked apartment with only two other occupants - his niece and a servant. Neighbour and lawyer Otis Landon follows the clues to try and prove the niece, Janet Pembroke, innocent.
As would seem to be normal in these stories most of the tale and clues are revealed before the detective Fleming Stone appears and solves the case. But still an enjoyable story.
