I couldn't... But maybe you can.
The main character is an L.A. detective (recently promoted, I believe), and the book starts quickly with him witnessing the murder of a criminal by his senior peers, iirc in a parking garage, and he is troubled by how to handle it. This is one plot, intertwined with that of a serial killer on the loose. I cannot recall how it all comes together, but basically the young detective winds up in a race to catch the serial killer before being killed or framed by his senior peer detectives, and also to catch the killer before the killer catches him. He tracks the killer to Europe, is helped by a detective over there (Russian I believe). Another sub-plot is this detective has an adult sister who had some trauma so he cares after her... and it turns out the killer is some sort of Duke or something who is about to marry her in Europe..and a big blazing shoot-out in a train garage was one scene. Also the end came together at a museum.
Sounds pretty silly the way I described it, but it actually was a pretty good read...kept me turning pages...
