"Well, that's settled, by Gad," he said breezily. "If you've finished your drink, my dear fellow, we'll get along at once."

They went in a taxi to the Colonel's apartment, a small suite at the lower end of Clarges Street. Uppingdon burbled on with engaging geniality, but Mr. Immelbern kept his mouth tightly closed and wore the look of a man suffering from toothache.

"How about some caviar sandwiches and a bottle of wine?" suggested the Colonel. "I can fix those up myself. Or if you'd prefer something more substantial, I can easily get it sent in."

"Caviar sandwiches will do for me," murmured Simon accommodatingly.

There was plenty of caviar, and some excellent sherry to pass the time while the Colonel was preparing the sandwiches. The wine was impeccable, and the quantity apparently unlimited. Under its soothing influence even the morose Mr. Immelbern seemed to thaw slightly, although towards the end of the meal he kept looking at his watch and comparing it anxiously with the clock on the mantelpiece. At a quarter to two he caught his partner's eye in one of the rare lulls in the Colonel's meandering flow of reminiscence.

"Well, Sir George," he said grimly, "if you can spare the time now—"

"Of course," said the Colonel brightly.

Mr. Immelbern looked at their guest, and hesitated again.

"Er — to deal with our business."

Simon put down his glass and rose quickly.
