A/N: When I said 'sometime' I swear I did not have a month in mind.
I dared to look around when the noise had subsided. Wiggins had thrown himself to the ground and was scrambling forward. Holmes when to meet him halfway and helped the boy up. Both of them looked perfectly fine, though Holmes insisted on checking Wiggins.
I felt fine as well, and I wondered if for once Holmes and I would both finish a case uninjured. I looked to the villain, wondering if my shot had made it home.
He was in the process of fleeing, and I noticed no blood. A smoldering object lying on the ground did catch my eye and I went over to it.
The two bullets had collided. They were now fused together in a circular shape.
"Wow, that must've been one shot in a million!" Wiggins said, coming up behind me. He sounded a little shaken. Indeed, I had never even considered the possibility of ever doing that, though during my time in Afghanistan someone found a pair of bullets like this. Holmes silently picked up the spectacular shot and pocketed it.
We got Wiggins home safely and returned home ourselves. Holmes still had the two bullets, and I didn't mind letting him keep them.
We never were the ones to net the murderer, but now, among Holmes' growing collection of souvenirs, there were two fused bullets.
