The title in French "Engrenages" literally means 'gears'. However this word is also used figuratively to mean 'complications' (apparently by Jean Paul Sartre). The English title "Spiral" doesn't carry anything like the same power. The story is immensely complex and dark with interlocking relationships, corruption and deceit. How does "Spiral" even begin to hint at this? I would have liked a better attempt at an English title. Some of my own suggestions are "Convolutions", "Wheels within Wheels" even "Enmeshed" or "Cogs". Can anyone else come up with a better idea? Apart from this quibble, I am completely gripped by the series and have had to reschedule my life around the late programming. I never fall asleep during the program and on occasion lie awake thinking about it afterwards.
