"The night that I landed upon Tresco," I said, "we crossed the Castle Down, I nearly fell on to the roof of the shed, where all the dead sailormen were screeching in unison."
"Yes!" said Dick, in a low voice, and I too looked around me to see that we were not overheard. Dick moved a little nearer to me with an uneasy working of his shoulders.
"Do you remember the woman who passed us?" I asked.
"You said it was a woman."
"And it was."
I had the best of reasons to be positive upon that point. I had scratched my hand in the gorse and I had seen the blood of my scratches the next day on the dress of the woman who had brushed against me as she passed. That woman was Helen Mayle. Had she come from the shed? What did she need with the key?
"Is that shed ever used?" I asked.
"Not now."
"Whom does it belong to?"
He nodded over towards Merchant's Rock.
