"Raindrops, lit red by the neon sign, ran slowly down the window, ,..." (Alan Furst)

"19 March.
The seers of weather predicted the rainiest spring of the century, and so it was when Carlo Weisz returned to Paris. It dripped off the brim of his hat, ran in the gutters, and did nothing to improve his state of mind. ... Salamone was also happy to see him, though not for long, when they met at the bar near his office. Raindrops, lit red by the neon sign, ran slowly down the window, and the bar dog shook off a great spray of water when she was let in the door."
