The Shadow Puppet (Inspector Maigret)

"One by one the lighted windows went dark. The silhouette of the dead man could still be seen through the frosted glass like a Chinese shadow puppet. A taxi pulled up. It wasn't the public prosecutor yet. A young woman crossed the courtyard with hurried steps, leaving a whiff of perfume in her wake."

Summoned to the dimly-lit Place des Vosges one night, where he sees shadowy figures at apartment windows, Maigret uncovers a tragic story of desperate lives, unhappy families, addiction and a terrible, fatal greed.
