Harry looked and looked at the words on the paper. What did it mean? Harry was smart and thought he had a good idea of who sent him the letter. He didn't know who it was exactly, but he thought he knew the person. Guppy's attacker? Could it be the person who stabbed the young Guppy Sandhu?

Harry looked up from the letter and was surprised to see that an hour had passed. It had now been three hours since he had helped Guppy in Resus. He stood up and made his way to reception. However, he need not have gone so far because Charlie Fairhead ran up behind him.

'Harry!'

'Charlie, any news on Guppy?'

'Yes. He's doing fine, I'm glad to say.'

'Where is he?'

Charlie gave the directions to the Harry and carried on up the corridor. Harry turned and headed for the lift. He pressed a button and stepped inside. As he stepped out on his desired floor, he paused. He decided against what he had been thinking and went to Guppy's room. He knocked softly and opened the door as slowly and quietly as he could.

Guppy lay on the bed, his eyes shut and his face pale. His hair, which was normally bushy and springy, now drooped in flat layers. Harry was slightly startled to see him like that. He had always known Guppy to be lively and active. He approached the bed and stood, smiling slightly in the friendly way he was known to have when his friends were suffering. He waited to see if Guppy had noticed him.

'…Harry…?'

'Yes,' Harry whispered, 'it's me. How are you feeling?'

'Awful… I'm not as bad as I was, but… I'm still… you know…'

'Scared?'

'Yeah.'

'Well, there's no need to be scared now, my friend. You're in safe hands here.' Harry paused and then added, 'Guppy, why are you here? I thought I sent you home. And your name's not down for the night-shift.'

Guppy winced, not so much with the pain in his abdomen, but with the embarrassment he had felt earlier when he had accused his boss of being involved in a drugs trial. He looked up at Harry and said quietly, 'I came to apologise for… for thinking that you were involved in the…'

'Don't say anymore, Guppy. Just concentrate on recovering, there's a good chap.'

Guppy smiled at Harry weakly. Harry patted Guppy's shoulder gently and said, 'Now, get some rest. I'll come and see you again later.'

Harry left the quiet, dark room and returned once again to his office. He worked for a further two hours and then stopped to rest his eyes. He was determined not to fall asleep again in case he was needed urgently. He decided to get a breath of fresh air. He stood up and made his way down the corridor towards reception. He entered the brightly lit room and walked through the entrance doors. He breathed in deeply and exhaled the cold night air. As he was about to return to the hospital, he heard a sudden commotion behind one of the parked ambulances that stood outside the building. He ran towards the sound.

A terrible sight met his eyes. He saw Luke Warren the paramedic lying on the floor, blood staining the green uniform he wore. Harry noticed a shadowy figure running away into the distance. If there had been anyone else to help Luke at the time, Harry would have tried to get a better look at the assailant. Instead he crouched down next to the stricken worker.

'Luke! Luke, can you hear me? Luke!' He looked up from the bleeding man and let forth a loud bellow of, 'HELP! I NEED HELP!'

A moment later, he was joined by Tess Batemen and Charlie. Looking shocked, Tess ran back to the hospital to get more nurses. They soon came running with a trolley. With some difficulty, Harry, Charlie and the rest managed to get their friend onto the trolley. They wheeled him into reception and straight through to Resus. Claire Guildford, who, against her better judgement, had decided to take the night-shift, stared at the man on the trolley. The young nurse ran after the group heading to Resus and tried to get close to Luke.

'Luke! LUKE!' she screamed. Charlie took her by the shoulders and led her to the relatives' room to calm down. She screamed at him to let her go with Luke but he stuck to his guns and didn't let go.

'Claire, calm down, darling. Harry will see to Luke. Sit down, sweetheart.'

Claire sank into the chair and Charlie put his arms around her. She lent her head against his shoulder and started to sob uncontrollably while Charlie hugged her gently, speaking to her in a soothing voice.

'It's OK,' he said quietly, 'It's all right.'

Claire still sobbed into Charlie's shoulder. She couldn't stop. She had been avoiding Luke because of the shocking discovery she had made earlier that day. Her brother had recently died and Claire had found a videotape that showed how he had come to have his fatal fall. Luke had lied to her to protect his ex-wife, Bex Reynolds. Now all Claire could think of was Luke dying too.

'He's going to die, isn't he Charlie?' She said, tears pouring like rain from her eyes.

'Shh… don't think things like that, darling. They're doing everything they can in there. You know they are. Come here.' And he pulled her closer to him, comforting her.

In Resus, Harry, Abs and Tess were treating Luke's wound. It was a stab-wound; the very kind that Guppy had received only a few hours before. Harry dressed the wound and gave Luke oxygen to help him breathe.

'Come on, Luke.' He murmured as he worked. 'Don't give up.'

Luke's eyes were wide with fright and his face was pale and sweaty, just like Guppy's had been. Harry and Abs finished up working on him and Tess and three other nurses wheeled him away to theatre. Harry peeled the gloves off his hands and discarded them. He turned to Abs, like he had done before.

'This can't be a coincidence.' He said quietly.

'No,' Abs replied, 'No, it can't. Do you think it was the same person or what?'

'How can anyone know that, Abs? Guppy was caught by surprise and he can't remember anything now anyway… and Luke didn't make a sound until it had happened. Nobody knows what's going on.' Harry said sternly and then, seeing Abs' face, he added, 'I'm not angry at you, Abs. I'm sorry I was snappy. I'm just worried. Two of my employees attacked in the same night.'

Harry returned to his office as he had to write up another report because of Luke's stabbing. He sat down, drew a piece of paper towards him and bent his head, ready to begin. It was then he saw the writing. He read it, and his eyes widened. He gasped.

Two now… you're getting careless.
