Hannasyde was awaiting them in the library still with Neville. North said to him, with a slight, rueful smile: "We owe you an apology, Superintendent. I rather think we've rendered ourselves liable to criminal prosecution."

"Yes, absolutely.,

"And you heard Fletcher returning towards the house just before you left the study?"
