"But if Marden's account is true--"

"West, as he lost consciousness, saw Marden go in exactly the same
way."

"Marden was seated by the open window, but I cannot conjecture how
any one can have got at West, who sat by the table!"

"The case of Marden is little less than remarkable; he was some
distance from the window. No one could possibly have reached him
from outside."

"And the constable?"

"The constable can give us no clue. He was suddenly struck down,
as the others were. I examined the safe, of course, but didn't
touch it, according to instructions. Someone had been at work on
the lock, but it had defied their efforts. I'm fully expecting
though that they'll be back to-night, with different tools!"

"The place is watched during the day, of course?"

"Of course. But it's unlikely that anything will be attempted in
daylight. Tonight I am going down myself."

"Could you arrange that I join you?"

"I could, but you can see the danger for yourself?"
