This book would, perhaps, have been bearable if there had been any credibility in the plot but that was very definitely not the case. The story involves a Shakespearian scholar following a trail towards some previously undiscovered Shakespeare documents, jumping around between Europe and the US, closely followed by a serial killer intent on finding the same documents. The trail is one incredibly improbable lucky guess after another and the killings even too painfully contrived for a typical fictional murderer. It all fell to pieces in the final climatic scene were the author herself lost track of which protagonist had the vital documents and they suddenly turned up, unexplained and impossibly under the circumstances, in the rival's hands. It was hard to keep going after that because obviously nothing was necessarily going to hold together if not even the author, editor and proof-readers were paying attention. Only worth reading if with a very robust suspension of disbelief and a rock-hard disregard for continuity errors.
