It has to be small enough to

"I need the chopper to bring me a bug, a miniature radio beacon, the kind you plant on someone you need to follow. It has to be small enough to fit into a bottle cap." "How long does the transmitter need to operate?" "Forty-eight hours." "No problem. They should have that at police headquarters in Inverburn." "One more thing. I need a bottle of perfume—Diablerie." "They won't have that at police headquarters. They'll have to break into Boots in the High Street." "We don't have much time— Wait." Olga was saying something. Toni looked at her and said, "What is it?" "I can give you a bottle of Diablerie, just like the one that was on the table. It's the perfume I use." "Thanks." Toni spoke into the phone. "Forget the perfume, I've got a bottle. How soon can you get the chopper here?" "Ten minutes." Toni looked at her watch. "That might not be fast enough." "Where's the helicopter going after it picks you up?" "I'll get back to you on that," Toni said, and she ended the call. She knelt on the floor beside Kit. He was pale. His eyes were closed, but he was not asleep: his breathing was shallow and he trembled intermittently. "Kit," she said. He did not respond. "Kit, I need to ask you a question. It's very important." He opened his eyes. "You were going to meet the customer at ten o'clock, weren't you?" A tense hush fell on the room as the others turned and listened. Kit looked at Toni but said nothing. She said, "I need to know where you were going to meet them." He looked away. "Kit, please." His lips parted. Toni leaned closer. He whispered, "No."
