The steamers of the Irrawaddy flotilla have a corrugated-iron roof over the top deck.
The Thug must have been lying up there as the Colassie passed on the deck below."
"But, Smith, what is the motive of the Call?" I continued.
"Partly religious," he explained, "and partly to wake the victims!
You are perhaps going to ask me how Dr. Fu-Manchu has obtained power over such people as phansigars?
I can only reply that Dr. Fu-Manchu has secret knowledge of which, so far, we know absolutely nothing; but, despite all, at last I begin to score."
"You do," I agreed; "but your victory took you near to death."
"I owe my life to you, Petrie," he said.
"Once to your strength of arm, and once to—"
"Don't speak of her, Smith," I interrupted.
"Dr. Fu-Manchu may have discovered the part she played!
In which event—"
"God help her!"
CHAPTER XVI
UPON the following day we were afoot again, and shortly at handgrips with the enemy.
In retrospect, that restless time offers a chaotic prospect, with no peaceful spot amid its turmoils.
All that was reposeful in nature seemed to have become an irony and a mockery to us—who knew how an evil demigod had his sacrificial altars amid our sweetest groves.
This idea ruled strongly in my mind upon that soft autumnal day.
"The net is closing in," said Nayland Smith.
"Let us hope upon a big catch," I replied, with a laugh.
Beyond where the Thames tided slumberously seaward showed the roofs of Royal Windsor, the castle towers showing through the autumn haze.
The peace of beautiful Thames-side was about us.
This was one of the few tangible clews upon which thus far we had chanced; but at last it seemed indeed that we were narrowing the resources of that enemy of the white race who was writing his name over England in characters of blood.
To capture Dr. Fu-Manchu we did not hope; but at least there was every promise of destroying one of the enemy's strongholds.
We had circled upon the map a tract of country cut by the Thames, with Windsor for its center.
Within that circle was the house from which miraculously we had escaped—a house used by the most highly organized group in the history of criminology.
So much we knew.
Even if we found the house, and this was likely enough, to find it vacated by Fu-Manchu and his mysterious servants we were prepared.
But it would be a base destroyed.
We were working upon a methodical plan, and although our cooperators were invisible, these numbered no fewer than twelve—all of them experienced men.
Thus far we had drawn blank, but the place for which Smith and I were making now came clearly into view: an old mansion situated in extensive walled grounds.
Leaving the river behind us, we turned sharply to the right along a lane flanked by a high wall.
On an open patch of ground, as we passed, I noted a gypsy caravan.
An old woman was seated on the steps, her wrinkled face bent, her chin resting in the palm of her hand.
I scarcely glanced at her, but pressed on, nor did I notice that my friend no longer was beside me.
I was all anxiety to come to some point from whence I might obtain a view of the house; all anxiety to know if this was the abode of our mysterious enemy—the place where he worked amid his weird company, where he bred his deadly scorpions and his bacilli, reared his poisonous fungi, from whence he dispatched his murder ministers.
Above all, perhaps, I wondered if this would prove to be the hiding-place of the beautiful slave girl who was such a potent factor in the Doctor's plans, but a two-edged sword which yet we hoped to turn upon Fu-Manchu.
Even in the hands of a master, a woman's beauty is a dangerous weapon.
A cry rang out behind me.
I turned quickly. And a singular sight met my gaze.
Nayland Smith was engaged in a furious struggle with the old gypsy woman!
His long arms clasped about her, he was roughly dragging her out into the roadway, she fighting like a wild thing—silently, fiercely.
Smith often surprised me, but at that sight, frankly, I thought that he was become bereft of reason.
I ran back; and I had almost reached the scene of this incredible contest, and Smith now was evidently hard put to it to hold his own when a man, swarthy, with big rings in his ears, leaped from the caravan.
One quick glance he threw in our direction, and made off towards the river.
Smith twisted round upon me, never releasing his hold of the woman.
"After him, Petrie!" he cried.
"After him.
Don't let him escape.
It's a dacoit!"
