Shortest Way to Hades (SIGNED)

From classicmysteries.net: "We are told quite often that the road to Hell is paved with good intentions. Certainly the intentions of the lawyers working to protect the assets of a very large (and very English) estate from taxation had the best of intentions. Without a change to the legal trust which had originally been set up, the heirs of a five million pound estate would have to pay more than three million in taxes. A little practical - and perfectly legal - editing of the trust agreement would reduce that bill very considerably. No, the intentions were certainly good. It was hardly their fault that someone decided a certain short cut along that well-paved road was going to be needed." And when that shortcut involves murdering one of the beneficiaries, Oxford legal scholar Hilary Tamar is called upon by her young friends practicing at Lincoln's Inn to unravel the mystery before the murderer eliminates another inconvenience - permanently.
