“I watched her closely many hours last night, but I fear I missed those precise details,” laughed Warden. “I shall correct the lapse at the earliest opportunity.”

“That sort of definite fact assists one’s judgment. Paint and rig can be altered, but structural features remain. I recall the case of the Sylph, a foreign cargo–steamer loaded to the funnel with dynamite, and about to pass Port Said at a time when it was peculiarly important to the British fleet that the canal should remain open. She resembled a hundred other disreputable–looking craft of her class, but a lieutenant on the Cossack had seen her a year earlier at Bombay, and noticed a dent in the plates on the port bow. His haphazard memory settled a delicate and complicated discussion in Pekin. Good morning! Don’t forget to send your address.”

Standing in Downing Street to light a cigar, Warden glanced up at the stately building he had just quitted. His views on “red–tape” officialdom had undergone a rapid change during the past hour. It was borne in on him that generations of men like himself had come from the ends of the earth to that storehouse of secrets, and each was convinced that he alone could reveal the solemn tidings which might be the forerunner of modern Europe’s Battle of Armageddon. And the Under Secretary was called on to hear every prophet! From such a standpoint the presence in England of a half–caste Portuguese and three full–blooded negroes dwindled to insignificance. True, the Under Secretary had listened, and Warden almost shivered when he realized how narrow was his escape from committing the grave error of discounting his hearer’s sympathy and measure of comprehension.

It was not his business to ask questions, but he gathered that others than himself were alive to the dangers that might spring from a conference between semi–rebellious subjects of Britain in West Africa and the ruler of a mighty nation pent within cramped confines for want of colonies. Oddly enough, the bent plates of the dynamite–laden Sylph suggested a strange connection between the carved gourd and the strained position of affairs in the Cameroons. He had no manner of doubt that when the royal yacht crashed into a sunken wreck the previous day it liberated the calabash, which forthwith drifted into the Solent, and escaped notice until discovered by Evelyn Dane. Suppose she had not seen it? All their subsequent actions would have been affected. He might never have known of the strange gathering on board the yacht.

“Queer train of circumstances!” he thought. “If only I could use a pen, what a romance I might contrive with that as a beginning—and this,” he added, when, in searching for a box of matches, his fingers closed on the crisp roll of skin, “this as the frontispiece.”

He hailed a cab. He wanted to open the bag left at the railway terminus and deposit the gourd with the rest of his belongings in a small flat hired months ago as a pied–a–terre. His stock of cigars needed replenishing, and the weird document that had just made its presence felt reminded him that a Portuguese dictionary was lacking. A glance at his watch showed that he could not reach Cowes until a late hour, so he resolved to pass the night in town, go to a theatre, and return to the Nancy next morning.

From Waterloo, therefore, he telegraphed to Peter:

“Remaining here until to–morrow. Keep your weather eye open.”

He was sure that his friendly factotum would grasp the full meaning of the second sentence, but he would have been the most surprised man in London could he have known that Peter at that moment was plying the three men of Oku with gin.
