Michael Dobbs’ novel The Edge of Madness is rather on the edge of disappointing.
For a cyber-thriller there is too little cyber, too little [or or even none] ‘wow, this is what technology can do nowadays.’ For a political thriller there is too little politics, scheming, plotting even though there are four different heads of their states involved in the plot. The characters are mostly cardboard cut-outs. Only the reluctant ‘hero’ gets a little more depth, some glimpses of his darker past.
The plot is rather constructed. The solution to the big problem is too convenient. In the end, the evil guys are all dead or get what they deserve. At the end of the episode all is back to normal.
