“It is Chaven, the royal physician. I’ve told you about him. As to why…”

“Crawled.” Chaven’s laugh was dry and painful to hear. “Crawled across the castle in darkness…to here. I need help with my…my wounds. But I cannot stay. You are in danger if I do.”

“Nobody’s in anywhere near as much danger as you, looking at those burns,” Opal said, scowling at the physician’s pitiful, crusted hands. “Hurry, bring me some water and my herb-basket, old man, and be quiet about it. We don’t need the boy underfoot as well.”

Chert did as he was told.

By the time Opal had finished cleaning Chaven’s burns with weak brine, covered them with poultices of moss paste, and begun to bind them with clean cloth, the wounded physician was asleep, his chin bumping against his chest every time she pulled a bandage snug.

Opal stood and looked down at her handiwork. “Is he trustworthy?” she asked quietly.

“He is the best of the big folk I know.”

“That doesn’t answer my question, you old fool.”

Chert couldn’t help smiling. “I’m glad to see the difficulties we’ve been through lately haven’t cost you your talent for endearments, my sweet. Who can say? The whole world up there is topsy-turvy. Up there? We have a child of the big folk living in our own house who plays some part in this war with the fairy folk. Everything has gone mad both upground and here.”

“Injured or not, I won’t have the fellow in the house unless you tell me he can be trusted. We have a child to think of.”

Chert sighed. “He is one of the best men I know, ordinary or big. And he might understand something of what’s happened to Flint.”

Opal nodded. “Right. He’ll sleep for hours—he drank a whole cup of mossbrew, and he can’t have much blood left to mix it with. We’d best get what sleep we can ourselves.”

“You are a marvel,” he told her as they climbed back under the blanket. “All these years and I still cannot believe my luck.”

“I can’t believe your luck, either.” But she sounded at least a little pleased. Better than that, Chert had seen in her eyes as she tended the doctor’s wounds something he had not seen there since he had brought Flint back home—purpose. It was worth a great deal of risk to see his good wife become something like herself again.

Chaven could barely hold the bread in his hands, but he ate like a dog who had been shut for days in an abandoned cottage. Which, as he began to tell Chert and Opal his story, was not so far from the truth.

“I have been hiding in the tunnels just outside my own house.” He paused to wipe his face with his sleeve, trying to dab away some of the water that had escaped his clumsy handling of the cup. “The secret door, Chert, the one you know—there is a panel that comes out of the wall of the inside hallway and hides the door from prying eyes. I closed that behind me and went to ground in the tunnels like a hunted fox. I managed to bring a water bottle that had gone with me on my last journey, but had no time to find food.”
