Dave Wardell’s breath came thick and fast as he struggled to keep up. In the dark alley ahead, he could make out the shape of the fleeing suspect(嫌疑人),with his police dog, Finn. The 16-year-old boy they were chasing was suspected of armed robbery, but Dave wasn’t too worried. He and Finn had been in similar situations dozens of times, and they knew exactly what to do. They were a brilliant team. Police dogs like Finn follow a lengthy training program, learning skills such as how to trace a suspect’s scent(气味)for up to four miles and how to chase and catch a suspect. In seven years, Finn had helped bring more than 200 criminals. He was brave, bold and curious, and would do anything to protect his master.

Dave thought that night would be no different. Up ahead, he saw the suspect throw himself over a fence. Finn was on him in a second, pulling him back down. In a moment of absolute horror, Dave saw him pull a long piece of bloody metal from Finn’s chest, Dave realized it was a 10-inch hunting knife. Finn was in pain, but didn’t let go of the boy’s leg.

Dave just had time to hit an emergency button on his radio. The suspect, on the fence, pulled the knife up high and aimed at Dave’s neck. In an instant, Finn jumped between them, and the knife came crashing down on Finn’s head and Dave’s hand. Straight away, Finn got hold of the boy again. Dave caught the attacker and threw him on the ground so he let go of the knife.

In time, officers surrounded the attacker, pinning him to the floor. Dave gave Finn the signal to let go, and only then did Finn drop his head to the ground.
