A/N: Set during SPECK.
Danger
After seeing the bell-pull that did not ring, the bed that was clamped to the floor, the chair and the tied dog leash, there had been no doubt in his mind as to how the murder had been committed. But the safe remained invariably closed, and there was no proof any court would accept.
Therefore, he had to see with his own eyes, confirm his deductions and turn theory into fact. Truth be told, he was more than grateful that he would not face this death-trap of a room alone. But he could not allow Watson to walk into the danger unawares.
