"Into the Fire" is flush with the elements of a first-rate thriller. These include a tightly plotted story with surprising turns, a sympathetic protagonist with lots of grit, menacing but sympathetic villains, terrific action writing, and a nifty ending, which leaves the falsely defamed heroine both happy and whole. Especially impressive to me was the highly visual nature of the writing, which will convert easily to hit movie with, say, Julia Roberts, in the lead. Lovers of London will also enjoy following the heroine, Helen Jencks, as she moves about town. I give the book my top thriller rating of five beach-towels.
