Like The Green Ripper, this is one of the few McGee novels that I had only read once - and my memories of it were less than glowing. It has been years, but all I could remember about Silver was the overwhelming sense of anxiety and, of course, the surprising reveal at the end. (Which, I'm sorry to say, will be inevitably spoiled during the course of the review.).
Also like The Green Ripper, I was failing to account for The Lonely Silver Rain being part of the series and only appraising it as a stand-alone mystery. If Green is the high-intensity, action-packed turning point in the series, Silver is the concluding challenge.
The Green Ripper is the bit in "Con Air" where Nicholas Cage works his way through the plane, dramatic Ranger music playing, angry cons falling left and right as he finally unleashes his inner whoopass and saves the day. The Lonely Silver Rain is the final car chase in the same movie - speeding after John Malkovich on his stolen fire truck. After a plane crash, this may seem completely unnecessary, but as a character, Nick Cage needed the personal resolution of taking out the bad man and honourably reclaiming his place in society.
