Shadow Unit 1, by Will Shetterly

This is a very clever concept done quite well.   The novel is written to give the reader the feel of watching a television series, and it works.   The Shadow Unit is a group within the FBI's behavioral analysis unit whose cases are too off for normal processing - think X Files.

Like a television series, there are a number of writers.  Unfortunately though the group couldn't keep up the momentum:  I was eager to read volume two but didn't make it very far before giving up in despair.  But this first book is worth reading.
