Martin, an ordinary, middle-class accountant wins some money playing the football pools, and decides he's going to give at least half of it away. He comes up with a list of deserving recipients - his cleaner's sister-in-law, a child who needs surgery, a couple of friends of friends - and writes some letters to set his plan in motion. It's a simple act of kindness, with only a hint of self-interest. On the heels of his first charitable act, a gift of flowers appears at his door, and he quickly falls hard for the young woman who delivers them. Something has been set in motion, and by the time Martin puts the pieces together, it will be too late. I couldn't put it down, and I marveled at how Ruth Rendell put it all together.
Martin Urban is a quiet bachelor with a comfortable life, free of worry and distractions. When he unexpectedly comes into a small fortune, he decides to use his newfound wealth to help out those in need. Finn also leads a quiet life, and comes into a little money of his own. Normally, their paths would never have crossed. But Martin’s ideas about who should benefit from his charitable impulses yield some unexpected results, and soon the good intentions of the one become fatally entangled with the mercenary nature of the other. In the Lake of Darkness, Ruth Rendell takes the old adage that no good deed goes unpunished to a startling, haunting conclusion.
