Kidnapping the secretary...
About halfway through the movie, the secretary/assistant from the intelligence service leaves the office for the day...and these guys on motorbikes follow and presumably kidnap her, since she ends up back at Pelham House.
1. How did they even know who she was ? She spent all her time in the office. How would they know she worked for MI-6 and how would they know she had anything to do with the investigation into Pelham house ?
2. The men were on motorbikes. (Nice furry vests, by the way) If they were on motorcycles and they knocked her unconscious, how the hell did they transport her from a busy london street back to Pelham House, out in the country ?
3. The motorcyclists/guards are revealed to be vampires, as they are shot numerous times and they 're-generate' and heal instantly. How the heck are they out in the daylight ?
