P.d. James said this quote

Before he turned again the to the car his eye was caught by a small clump of unknown flowers. The pale pinkish white heads rose from a mossy pad on top of the wall and trembled delicately in the light breeze. Dalgliesh walked over and stood stock still, regarding in silence their unpretentious beauty. He smelt for the first time the clean half-illusory salt tang of the sea. The air moved warm and gentle against his skin. He was suddenly suffused with happiness and, as always in these rare transitory moments, intrigued by the pure physical nature of his joy. It moved along his veins, a gentle effervescence. Even to analyse its nature was to lose hold of it. But he recognized it for what it was, the first clear intimation since his illness that life could be good.
