Harry picked up the phone and called the police.

'Send someone over now! It's serious! We've had three members of staff stabbed in less than twenty-four hours. And I've been receiving anonymous messages that seem to be from the culprit.'

Half an hour later there were police officers swarming all over the hospital. One of these police officers was Will Manning, a man that Harry was less than happy to see. Harry led him into his office and offered him a seat. He knew that he would have to try and tolerate Will the best he could.

'Why didn't you phone me before, Harry?'

'There was no need to. It was just Dr Sandhu. A one-off, we suspected.'

'But, after that? You should have called the police.'

'Yes, OK, we should have called the police. Can we just get this sorted before anything else untoward happens?' then Harry added through gritted teeth, 'Please.'

Will stood up and walked out of the room. Harry followed and was about to go the same way as Will, but then spotted an employee he didn't expect to see. He checked that Will hadn't noticed. He hadn't. Harry slipped up the corridor and caught up with his worker.

'Selena, what are you doing here?'

'What does it look like; I'm working.'

'You should be resting.'

'Will you stop worrying, Harry? It's getting on my nerves.'

'I'm sorry, Selena,' Harry said, hurt, 'I was only thinking of your health.'

'Well, don't. I'm a doctor, too, Harry. I don't need you telling me if I'm healthy or not.'

'I'm your boss and I say that you shouldn't be here.'

'You're a pain, Harry! You're a bloody pain!' Selena walked off up the corridor.

If it had been anyone else who had spoken to him like that, he would have called them back and reprimanded them severely. However, he didn't wish to cause Selena any more stress. He just hoped she would take it easy.

He sloped off, half annoyed and half worried. It wasn't a very nice feeling, and Will Manning going on at him about not contacting him sooner wasn't helping his mood at all. He found himself almost losing his temper with the police officer at more than one occasion, but managed to hold the anger back as he knew very well that it wouldn't help matters. He needed to cool off. He turned and headed for the car park.

He pushed open the door and the fresh air made him feel a little better. He tried desperately to think of how the attacker could get into the building, commit the crime and also find time to leave a note behind. He was pondering this when he heard a shout from his left. He turned to see Woody, the paramedic, running towards him. He had blood on his green uniform, Harry noticed.

'Woody!' Harry sprinted towards him and grabbed his shoulders, 'Are you all right? What's happened? Are you hurt?'

'It's… it's Selena.'

'Selena?' Harry was shocked out of all self-possession. He hurtled after Woody, 'SELENA!'

Selena lay, stricken, on the ground. Blood was seeping through her pale clothes. Harry ran to her and knelt down beside her, taking her hand in his.

'Selena… you're going to be all right. Can you hear me? It's all right.'

'…Harry… you're… you're not… a bloody pain…'

'Shh… it's OK, I don't care what you think of me at the moment. Just stay still.'

Woody had run to the building to get help and now Tess, Abs and several off nurses ran towards the couple on the ground.

'Bloody hell! Another one?' Abs gasped as he helped get Selena onto a trolley.

'So it seems…' Harry mumbled, still holding Selena's hand.

They wheeled her into Resus and Harry pulled on some disposable gloves. He began to dress the wound while Abs gave Selena the oxygen she so desperately needed. Harry worked, as ever, quickly and capably, but Selena was weak from her previous attack. She was slipping in and out of consciousness and her vision was blurring. One moment Harry would be right in front of her, the next, he was behind a misty cloud. He began to grow darker and darker, and he moved further and further away. His words of comfort and reassurance got fainter and fainter. Even as he began to shout her name over and over again, she could hardly hear him. She thought she heard the words, 'I love you…', but she was no longer in control of her thoughts. Her vision was completely gone and she heard no more.

'Selena! Her BP's dropped! Start CPR!'

Abs ran to Selena's side and started doing chest compressions. Harry manned the oxygen, squeezing the gas into Selena's nose and mouth at regular intervals.

'Stop; pulse check.' He said.

Abs ceased and Harry placed two fingers gently on the spot beneath Selena's chin. He felt for a pulse; nothing; not a single heartbeat.

'Carry on!' He commanded.

Abs resumed the compressions and Harry continued giving oxygen. Another cycle of CPR was carried out.

'Pulse check.'

Nothing.

'Continue!'

Another cycle.

'Pulse check.'

Still nothing.

'Resume!'

A fourth cycle.

'Pulse check.'

Not a trace of a pulse.

'Again!'

A fifth cycle.

Harry swallowed, 'Pulse check…' his voice was shaky and he could hardly get the words out. He placed his fingers on Selena's neck and felt. He hoped, wished and prayed that he would feel something – anything – that would indicate Selena was still with him. There was nothing. There was nothing at all. He was about to call for another cycle when the sound of the monitor at his side cut through his thoughts. It had been crying its monotonous cry all through the CPR and it still wailed now. Harry looked around at the faces of his fellow team-members. They were all looking back at him, waiting for his instruction. They were waiting for him to come to a decision. He had to decide whether Selena had another chance. He had to let her go.

'We've… we've completed five cycles. I think… I think we should… stop.' He stammered, 'Does everyone agree?' He secretly hoped that someone would disagree with him. He didn't want to be the one to choose death.

'I… I think Harry's right.' Abs' voice was quiet and he looked pale. He looked up at Harry and they exchanged a look of silent, unwanted, agreement.

'I agree.' Tess said.

There were nods of agreement from all assembled. Harry sighed deeply. He unhooked the oxygen pump from Selena's face and then looked at his watch.

'Resus abandoned at 6:53pm… good effort everybody; a really good effort. I'm proud of you all… and… and Selena would have been too.'

'I'm sorry, Harry.' Tess sympathised.

'So are we.' Abs whispered, indicating the team.

'I'd… I'd like to be alone with her please.' Harry said, quietly, trying and failing to keep the emotion out of his voice.

'Of course, Harry.' Tess said.

The nurses left Resus and went to their separate locations. Harry stood beside Selena and he allowed the tears to fall freely from his eyes.

'I love you… I hope you know that. I really love you…' he bent down and kissed Selena's pale, clammy forehead gently. His tears dripped onto her skin. He sank to his knees and buried his head in his hands, not keeping anything back. He sobbed bitterly. His tears stung his eyes; his face was red and damp. He was completely inconsolable. He knelt on the floor of Resus, Selena's blood on his hands and he wept. A scrunched up piece of paper flew through the window and hit the back of his head. He took his hands away from his face, leaving bloody fingerprints across his cheeks, and read the note.

Looks like she had two bloody pains to cope with in the end.
