Tell Me No Lies by Shelley Noble

Philomena Amesbury, Lady Dunbridge helped solve the murder of her  friend's husband and that makes her a somewhat more likely person for financier Luther Pratt to come to when a young man is murdered at his home. The night before, Phil had gone to a party at his house and met Perry Fauks, heir to the Copper, Coal and Steel fortune. This morning, he is dead.
The immediate suspect is Perry's valet but the death is being quickly hushed up and Phil wonders why. Add in a friend from England who was coming to meet with Perry to discuss selling her mines, Agnes, Luther's daughter who was engaged to Perry but seems to love the family secretary, and Agnes' cousin Maude who would love to have been the one in Agnes' shoes as well as a smattering of other characters and it is a conundrum indeed. And Phil's unknown benefactor is still pulling strings  and giving her hints and instructions on how to navigate this mystery.
The mysterious benefactor/spymaster is getting to be a little too much for me. I really hope that there will be more developments with him in the next book as it is getting to be too over the top right now.
