through the tubes and wires keeping Ralph alive. Then she advanced on the twins again.
Rich stepped over the policeman and edged round the far side of the bed. Ralphâs breathing was alreadybecoming ragged and laboured. Without taking his eyes off Colonel Shu, Rich lunged for the emergency pull-cord at the head of the bed.
In the distance, a buzzer sounded.
Shu gave a grunt of anger and ran for the door. She swiped the scalpel at Jade as she passed, but Jade easily avoided itâand as she stepped back, Jade kicked out. Her foot connected with Shuâs wrist and the scalpel spun away, clattering to the floor.
With another shout of anger, Shu turned and ran.
âGet help,â Jade yelled at Rich. âTell them what happened.â
âWhere are you going?â
âAfter her.â
Rich opened his mouth to protest, but Jade was gone.
Then a hand seized Richâs arm.

Jade was in time to see Colonel Shu disappear round the corner at the end of the corridor, her white coat billowing behind her as she ran. Jade set off in pursuit.
Round the corner, the corridor continued past several wards and store rooms. A white coat lay discarded on the floor, but Jade could see the womanâs distinctive black pigtail swinging behind her as she ran. There were signs hanging from the ceiling. Colonel Shu was heading for X-Ray, A&E, and the Main Exit.
There was a man mopping the floor. Colonel Shu didnât even slow down; she shoved the man aside and kept running. The mop bucket went flying, spilling grey water across the floor.
âSorry,â said Jade to the man, as she ran past withouthelping him up. Her feet were skidding on the slippery wet floor. She slid, and almost fell, but managed to keep going. As soon as she was sure of her balance, she pulled her mobile out of her pocket.
It was switched off. Sheâd done that when she came into the hospital. It seemed to take forever to turn back on again. As soon as sheâd entered her PIN and the handset unlocked, the phone rang.
âDad?â
âRich told me,â her fatherâs voice said at once. âWhereâs Shu headed?â
âTrying to get out through Accident and Emergency.â
âIâm on it.â The phone went dead.
âYeah,â said Jade, stuffing it back in her pocket. âSo am I.â
There were double doors made of heavy plastic hanging across the end of the corridor. They swung shut behind Shu, their weight almost knocking Jade over as she pushed through.
Shu was already on the other side of the Accident and Emergency waiting area. An elderly woman on crutches was coming through the door. She lurched to one side, somehow remaining upright, as Shu charged past. Then she lost her balance and began to fall. A crutch clattered to the floor.
Jade caught the woman as she fell. She helped her get her balance and picked up her crutch.
âThank you,â the old woman spluttered nervously.
âNo problem,â Jade told her. âGot to dash.â
Through the main doors. Jade skidded to a halt in the glare of the floodlights that illuminated the front of the hospital. A car park stretched away into shadows. Two paramedics were lifting a wheeled stretcher out of the back of an ambulance; its blue lights still flashing. There was no sign of Colonel Shu.
Then the ambulance began to pull away, its back doors flapping. One caught a paramedic on the shoulder as the ambulance moved. He gave a startled yell.
âWhoâs driving?â the other paramedic shouted in surprise.
Then both were leaping aside, pulling the stretcher out of the way as a car screeched up where the ambulance had just been. It was a silver-grey BMW. The passenger window was open. Through it, Jade could see her dad at the wheel.
Jade wrenched open the door and threw herself into the car.
âWhich way?â Chance asked.
Jade pointed. âFollow that ambulance!â
Ralph seemed to be unconscious
