From Amazon.com:

Cassidy is dead and Jack is guilty, that's for sure. But of what, exactly, we're not certain. Guilty is a first novel, but more importantly, it is an outrageous, hilarious, tangentially revealed story of guilt, sex, fame, God, murder, danger, suspicion, love and hate. Jack and Cassidy had great sex. In fact, Cassidy may have been Jack's ideal sex partner, which is of great importance when your life revolves around sex. But then Cassidy would do things to drive Jack mad, which certainly could be a motive for murder. Also, Jack is a big man, which gives him the physical means to overpower Cassidy. And they were together on the night that Cassidy was killed, which provided the opportunity. Then there's the fact that Jack has dreamed of killing Cassidy and is not feeling too surprised or even too terrible about his death. But did he do it?
