Then something happened--I can't go into details now--to arouse my suspicions.

I rummaged through the storage closet in my temporary office and looped his telephone wire with twenty feet of number twelve wire from a broken electric fan, and an unused transmitter.

Then, scrap by scrap, I picked up my first inklings of what was at that moment worrying the Foreign Office and the people at the Embassy as well.

It was the capture of the Gibraltar specifications by Prince Slevenski Pobloff.

When a Foreign Office secret agent telephoned in that Pobloff had been seen in Nice, I fought against the temptation for half a day, then I went straight to the ambassador and told him what I knew, but not how I came to know it.
