“Ah, I have not been to Spain.” He looked at his watch. “It is quarter-past four now. Perhaps we should go, eh? It has been very nice this afternoon.”

Graham nodded wearily. If Haller wanted Mr. Kuvetli “probed” he could do the probing himself. His, Graham’s, personal opinion was that Mr. Kuvetli was an ordinary bore whose conversation, such as it was, sounded a little unreal because he used languages with which he was unfamiliar.

Mr. Kuvetli insisted on paying for the coffee; Mr. Kuvetli insisted on paying the fare back to the wharf. By a quarter to five they were on board again. An hour later Graham stood on deck watching the pilot’s boat chugging back towards the greying land. The Frenchman, Mathis, who was leaning on the rail a few feet away, turned his head.

“Well, that’s that! Two more days and we shall be in Genoa. Did you enjoy your excursion ashore this afternoon, Monsieur?”

“Oh, yes, thank you. It was …”

But he never finished telling Monsieur Mathis what it was. A man had come out of the saloon door some yards away and was standing blinking at the setting sun which streamed across the sea towards them.

“Ah, yes,” said Mathis. “We have acquired another passenger. He arrived while you were ashore this afternoon. I expect that he is a Greek.”

Graham did not, could not, answer. He knew that the man standing there with the golden light of the sun on his face was not a Greek. He knew, too, that beneath the dark grey raincoat the man wore there was a crumpled brown suit with lumpy padded shoulders; that below the high-crowned soft hat and above the pale, doughy features with the self-conscious mouth was thinning curly hair. He knew that this man’s name was Banat.

CHAPTER SIX

Graham stood there motionless. His body was tingling as if some violent mechanical shock had been transmitted to it through his heels. He heard Mathis’ voice a long way away, asking him what the matter was.
