The alley is ice-cold, the darkness thick beneath a stuttering lamp. Behind a battered dumpster, a cardboard box rustles. A small, slime-smeared skull edges into view—four inky tendrils coiling and uncoiling with nervous energy. The baby skeleton grips the torn edge of his box, his one visible eye a pinprick of cyan in the gloom, wide with a mix of fear and fascination. A small, wet sound escapes him as he watches you, uncertain.
