Briefly I explained how I had met Upton, and how Mr. Gibbs had been introduced.

“Upton may not be what he pretends, you know,” Blythe replied. “They want us very badly at Scotland Yard, and that’s why the affair has been given over to Dyer. He’s the man who generally does the travelling on the Continent. But you know him well enough by reputation, of course. Everyone does.”

Mr. Gibbs’s intense interest in the car and its maker was thus accounted for. I saw how completely I had been taken in, and how entirely I was now in the renowned detective’s hands. He might already have been round to the garage, unlocked the “bonnet” with a false key, and seen the name “Napier” stamped upon the engine.

How, I wondered, had he been able to trace me? No doubt the fact that we had shipped the car across from Parkeston to Hamburg was well known to Scotland Yard, yet since that night it had undergone two or three transformations which had entirely disguised it. I was rapidly growing a moustache, too, and had otherwise altered my personal appearance since I posed as Bindo’s chauffeur in Scarborough.

“The Count, who is lying low in a small hotel in Düsseldorf, wants you to meet him with the car in Turin in a fortnight’s time—at the Hotel Europe. A Russian princess is staying there—and we have a plan. But it seems very probable that you’ll be waiting extradition to Bow Street if you don’t make a bold move, and slip out of Dyer’s hands.”

“Yes,” I said thoughtfully. “If Gibbs is really Dyer himself, then, I fear, that although I’ve been discreet—for I make a point of never telling my business to strangers—yet he has more than a suspicion that the car is the same as the one I drove daily on the Esplanade at Scarborough.”

“And if he has a suspicion he has probably wired to England for one of the witnesses to come out and identify you—Gilling himself, most probably.”

“Then we’re in a most complete hole!” I declared, drawing a long face.

“Absolutely. What are you going to do?”
