Investigation

Delbury was still in a bit of a mental fog, but he fastened on to that fact like a leech. There was some personal connection between the sender of those intimations and this murder.

 Shaughnessy went out and got the system busy. In five minutes the organization had slid into motion. The whole of the internknit workings of the Yard were proceeding swiftly and smoothly about their job of blocking up the exits of the country and notifying the police forces of every town throughout the kingdom.

 "The car ready?" asked Delbury, stricken his head out of the door.

 "Waiting outside," said Shaughnessy, coming back.

 "Right, out you go. I'm starting in five minutes. Must go along and see the chief. He knows all about it, I suppose?"

 "Sure; I phoned him at his house. He came straight down. 

 Wants to see you about it before you go."

 Delbury hurried round to the great office on the first floor.
