She might like Martin Amis' Night Train.

This book is told from the perspective of Detective Mike Hoolihan, a female detective who is charged with the task of finding the motivation for Jennifer Rockwell's suicide. Jennifer, a beautiful astrophysicist with a seemingly perfect life seems to have had no reason to kill herself. Thematically this book touches on cosmology and chaos theory, and their relation to the human condition as a possible motive for suicide.

Very noir-ish and a good read.
