Greg wasn't naïve enough to think that Donovan's participation had gone unnoticed by the gang leaders, someone would have been looking for her and noticed that she had left her flat late last night.

Until the other officer on Barrymore's payroll had been identified he knew he had to be careful who he trusted. Shutting himself in his office he picked up his mobile and dialled.

"I imagine you already know that my sergeant, Sally Donovan, is no longer staying in her flat." He said as soon as the phone was answered. "You may not be aware that she slept the night in my office and that I had the opportunity to question her thoroughly this morning."

"And?" Barrymore snarled.

"And I'm certain that she has no idea of the content or significance of the information she passed to Miss Smith." He said calmly, knowing the other man wouldn't believe him.

"Good. Where is she now?"

"Staying with friends. I've given her an easy case to work, something to take her mind off things."

There was a moment of silence at the other end of the phone.

"Be here in an hour."

"Yes Sir." But Greg was talking to a dead line. He thought quickly, and then dialled another number.

"Sally listen, stay in the flat, and keep the door bolted."
