"Thank you, sir," and as Solomon passed the lieutenant of police, Hammer caught an almost imperceptible wink.

What transpired in the other room Hammer never knew. For a long ten minutes those in the outer room listened to the hum of voices; then the commissioner reappeared, his face very red indeed.

"Lieutenant, put those two Dutchmen in cells and keep them there," he ordered succinctly, and sat down at his table while Solomon came out. For another few moments he wrote rapidly, then passed the paper to Solomon, who scrutinized it carefully and signed.

"I'm sorry this mistake occurred, Mr. Hammer," and the commissioner turned to him with extended hand, which the American grasped. "You'll have to go to Nairobi, of course; but I've accepted Mr. Solomon's bond for your appearance there. By Jove! Sergeant, take two men and get down to the wharfs; stop that fellow Jenson and bring him up here. We'll land him for perjury, Solomon!"

"Werry good, sir; and if so be as all's well, Mr. 'Ammer and I will bid you good day. We'll be back werry shortly, I 'opes, sir."

Once more in the free air, Hammer's first thought was for Jenson. As he started after the sergeant Solomon stopped him with a quiet chuckle and pointed out to a dot at the river-mouth.

"Too late, sir. But there ain't no 'urry, Mr. 'Ammer. There's a mortal lot in what the Arabs say about fate, sir; and if so be as a man's turned to evil ways, sir, then 'e's got to run 'is course, I says. Don't you fret, Mr. 'Ammer, we're a-going to send that 'ound to 'ell, sir."

To his surprise, the pudgy man led the way to the river, with Omar trailing after them, and, as they went, Solomon explained matters somewhat.

When he had left with Omar, the day before, he had missed the trail of Jenson and the askaris, owing to the fact that Jenson had been fetched back to Melindi by the police.

The askaris had perforce come with him, but had been sent on to the camp by launch, with a native for guide. Solomon had left no word of his whereabouts because he wanted Hammer at the plantation house where he could find him at a moment's notice.
