“The right place,” declared Cranston. “In fact the only place the blinks could have come from. That tower is on a direct line with the rear window of the parlor in Madame Mathilda’s house.”
Margo turned, surprised:
“How soon did you learn that?”
“Before we left Mathilda’s,” declared Cranston. “I took a good look from that window after I ripped away the blackout curtain.”
“Then why didn’t you send someone over there?”
“I did. Shrevvy took Hawkeye there to find if the way was clear. Harry Vincent and Cliff Marsland followed.”
“But the blinks occurred again -”
“Because Harry and Cliff sent them,” interposed Cranston, “to assure me that the roost was empty. It worried the lurker in the park. He was stationed where he was to cover the banshee’s trail.”
“But how could she slip through the cordon?”
“Very easily. A slide down the rock, slowed by the scrubby shrubs she encountered; then around to the gully.”
