The Rats Know Everything — Episode 4

He's a clean ghost. Then what do we do? If the system fails, we do it the old-fashioned way. Helen, canvas the scene with the sketch. I'll take this call time.

That sweet, rusty smell. That man reeks of every kind of blood-fresh rotten. He is soaked in it, delicious. Wait, I can understand rats and flies, too? That's him! Black hat, black mask! That's the killer! Don't let him run! Freeze! Police! Don't move!

Damn it. He got away. He knows these alleys like a sewer rat. Fiona, you sure that's our killer? Captain, my nose is razor hard. Even in that crowd, he reeked of blood. And cheap cigarette tar, 30 years worth. Add the mask and hiding, and I knew.

A sharp sense of smell. That would explain it. Exactly! His blood smink nearly got me. Drunk! Best perfume in the world! He really is marinated in it. Miss Cole, you've got sharp instincts.

We lost him. Come back to the station and help us track him.
