Model response

Rain lashed a dark London street, slicking cobblestones.  A shadowed figure slipped into a quiet alley.  Footsteps echoed, hollow, a chilling, lonely sound.  Then, a muffled shriek tore through the night.  A heavy thud followed, abruptly silencing screams.  Two bright eyes watched from a barred window.  Silence returned, broken only by the storm.  The alley remained empty, a gaping dark mouth.  A single, wet glove lay on the stones.
