Jack apparently decided in favour of fury. "You infernal rascal, Strong!"—he began, but Strong said something to the interpreter, who signed to the police, who promptly laid hold of Jack and me. It was too ridiculous.

"Strong, you"—Jack began again, and—"Gad, Strong, if I don't"—began I; but our policemen would not have us speak, and marched us up to our room, Strong and the interpreter following, bidding us in curt military fashion hold our tongues. It was a ridiculous position. I have laughed over the memory of it scores of times; I even felt inclined to laugh then. What could Strong's motive be in acting in this way? He could not want the picture, or he would never have given it to the skipper at Kiel. Had he thought better of it, and determined, if possible, to get us locked up here for a few days while he hurried away to Streatham to dig without us?

He couldn't, surely! Why, we could prove our right to the work of art by telegraphing to Kiel, and, if necessary, producing the skipper to witness to our purchase. Besides, he would have to prove his right to the thing before they could justly deliver it over to him.

It must be an act of spite, then, conceived in the simple desire to score one against us.

Of course the picture was found in my portmanteau. Equally, of course, we protested that it was our own, while Strong declared that we had stolen it from him during the voyage to Copenhagen. No less was it to be expected that upon seeing the work of art, both policemen and interpreters smiled grimly, and that one of them observed—

"Was ist aber Dass für ein Teufelskopf!"

In the end, the police took possession of the disputed picture, but allowed us to remain in peace at the hotel. This was, however, Saturday night, so that the examination into the matter of ownership which, we were informed, it would be necessary to hold, could not be brought into court before Monday.

This was very unfortunate, for if Strong should really have devised this little interlude with the sole desire to gain time, in order to reach the treasure-ground in Streatham a day or two before us, he had certainly gained his end.

It was in vain that we assured our captors that we could easily prove our title to the work of art by simply telegraphing to Kiel, to the man from whom we purchased it.

"That will be very good evidence on Monday, supposing that the seller appears in person," said the police. "Meanwhile, we will take care of the work of art, and on Monday you shall speak, and your friend here shall speak, and the plaintiff shall speak, and then we shall see to whom the beautiful picture belongs."
