leather-covered glass bottle of acid that Will had used to cut through the bars on her window was concealed in the wardrobe. The bars had been replaced, of course, and she had told Keren that Will had used acid. But the renegade knight assumed Will had taken it with him. There was no way for him to know that on the night of the escape attempt, Alyss had unthinkingly placed the bottle on top of the window frame. The following day, she had remembered it was there and secreted it in the little wardrobe that completed the furnishing of her prison, along with an uncomfortable bed, two chairs and a table. It certainly wasn't luxurious, but it could have been a whole lot worse. As for the acid, there would come a time when it might be useful, she thought.
Her eyes began to water with the strain of peering into the half-light outside the tower. She stepped away for a few seconds, rubbed them, blinked away the traces of tears and then set herself to watch once more.
When the moon set, she would begin her signaling.
Will was concentrating, the tip of his tongue protruding from the corner of his mouth as he encoded his message to Alyss. The dog lay under the table, and he rested his bare feet on her warm fur. From time to time, she grumbled contentedly, as dogs do. He glanced down at her, smiling.
"Nice of you to spend some time with me," he said."Where's your new friend?"
Her new friend was Trobar, the massively built, misshapen giant who was one of Malcolm's most faithful followers. The dog and Trobar had struck up an instant friendship. The giant had lavished her with all the pent-up affection of someone who had spent years with no person or creature to love. The dog seemed to sense his need and reciprocated, spending hours each day in his company. At first, Will had been slightly jealous. Then he realized how important the companionship was to Trobar and felt a little mean-spirited. The dog, he thought, was wiser and more kindly natured than he was.
He was working on Malcolm's table, and he glanced up as the healer entered the room. Malcolm looked with interest at the sheets of paper covered with letters and numbers. On one sheet, Will had written the message he wanted to send. On the second, he had translated the letters into code. He saw Malcolm's interest and, trying to seem casual, turned the original page facedown.
The Courier's code, known to the Diplomatic Service and the Ranger Corps, was a jealously guarded secret. But it was actually quite simple, and he didn't want to give Malcolm, ally though he might be, any chance to figure it out.
Malcolm smiled as he saw the gesture. As a matter of fact, he had been trying to get a glimpse. If he could see the original message, alongside the cipher version, he felt confident he could unravel the format of the code. The young man at the table was no fool, he reflected.
"Moonset in an hour or so," he said.
Will nodded. "We'll get going soon. I'm nearly finished."
"You send your message using a lamp, I take it?" Malcolm asked.
" That's right. It's only short because there's not a lot to tell her at the moment. It's just to let her know that we're watching and to set up a schedule for further messages."
The healer laid another sheet of paper on the table, along with a small, black, shiny pebble.
"Is there any way we could get this to her?" he asked. "I mean, could you tie it to an arrow and shoot it through the window? Something like that?"
Will shook his head and reached for his quiver. Malcolm had noticed that the young Ranger's weapons were always within easy reach.
" That's not a very reliable method. If you tie something to an arrow, it tends to fall off when you shoot it," he said."We do it a little differently."
He slid an unusual-looking arrow from the quiver and placed it on the table.
Instead of the usual razor-sharp broadhead at its tip, it had an extended cylinder. Malcolm examined it curiously. The cylinder was hollow. A threaded cap, surmounted by a
