Lincoln Rhyme's phrase 'walking the grid', where examination of every square inch of a crime scene will reveal evidence, no matter how miniscule, that will point to the villain, is severely tested in this short story. A young woman is found murdered in an underground car park. Amelia Sachs is sent to investigate. The area surrounding her has been obliterated by materials designed to obscure any evidence of the killer. The amount of collection boxes and bags is on a par with an episode of mass destruction. Rhyme finds the case as frustrating as any he can recall. A meticulous analysis of the subject matter and possibilities leads Rhyme to believe someone is using his classic text on 'Evidence Collection and Analysis' to cover their tracks.
The interaction between Rhyme's factual evidence-based approach and Sachs's psychology and policing of crime make for a formidable team. They are thorough in their own complementary ways as the tension builds to apprehend the culprit who has the hallmarks of a serial attacker. Working on minute leads, the plot is far from straightforward, absorbing with plenty of action, brainwork and some neat twists, the major one is cleverly unseen. Young police officer Marko works with Rhyme and Sachs in a diligent and engaging manner and adds to the book's character.
Jeffrey Deaver has written an enjoyable and suspenseful story. The format worked for me and is tremendous value. A short preview of his next novel 'The Kill-Room' is an addendum and is much anticipated.
