He flinched a bit when he saw it, but then straightened his posture in his best impression of a much more heroic man. He deepened his and answered the remaining girl.

Discovering bite marks on the man's neck and a gun by his side alarmed him. He asked the girl another question "Miss, there is definitely something strange going on, especially now that your friend has disappeared. It would be very helpful if you could give me some more details of how exactly these men 'fell down' "
