great, but unpopular professor murdered by his brother at Cambridge

I don't remember when I've read a mystery novel so incredibly bad that I could have written it myself. At least, though, if I'd written this one I would have tied up some loose ends that weren't quite explained in this story. I don't remember a more disjointed, loosely-plotted mystery. I was so uninterested from the start that I made myself finish this book.

a brief description, no spoilers:
Gillian Adams is a professor in Vancouver, Canada, and is taking a year's leave in London. She is invited to give a short talk at her old alma mater, Cambridge. One of her old professors is killed, leaving behind a list of suspects who want to do him in. Gillian is right there when it happens, as is her sometimes boyfriend Edward, who is a detective from Scotland Yard.

I do have to say that the ending was far from satisfying; it was too hurried as if the author realized that she needed to get the book done and just stuck in a solution. Personally, I kept wondering how the police came to the conclusion they did, because there's no leading up to it; it's just boom boom boom and they know who did it. I like to at least feel that the author gives me a chance to figure it out, by leaving clues to follow & characterizations that allow me to understand each principal character. Oh well. This is the last of her books I'll read. ( )
