The rain fell over Boston. Detective Mara arrived late tonight. The body lay cold upstairs. Windows were shattered from inside. A locked door concealed truth. Mara counted three bullet holes. Yet no gun was found. Photographs stared from dusty walls. Someone lied about that night. Mara whispered one simple question. Who had entered here first? Rain continued without mercy tonight.
