He passed the facades of great commercial mansions

Beale's finger traced the item for which the bill was rendered, and McNorton uttered an exclamation of surprise.
"Curious, isn't it?" said Beale, as he folded the paper and put it away in his pocket, "how these very clever men always make some trifling error which brings them to justice. I don't know how many great schemes I have seen brought to nothing through some such act of folly as this, some piece of theatrical bravado which benefited the criminal nothing at all."
"Good gracious," said McNorton wonderingly, "of course, that's what he is going to do. I never thought of that. It is in the neighbourhood of Horsham we must look for him, and I think if we can get one of the Messrs. Billingham out of bed in a couple of hours' time we shall do a good night's work."
They went outside and again questioned the policeman. He remembered the car turning round and going back the way it had come. It had probably taken one of the innumerable side-roads which lead from the main thoroughfare, and in this way they had missed it.
"I want to go to the '_Megaphone_' office first," said Beale. "I have some good friends on that paper and I am curious to know how bad the markets are. The night cables from New York should be coming in by now."
In his heart was a sickening fear which he dared not express. What would the morrow bring forth? If this one man's cupidity and hate should succeed in releasing the terror upon the world, what sort of a world would it leave? Through the windows of the car he could see the placid policemen patrolling the streets, caught a glimpse of other cars brilliantly illuminated bearing their laughing men and women back to homes, who were ignorant of the monstrous danger which threatened their security and life.
He passed the facades of great commercial mansions which in a month's time might but serve to conceal the stark ruin within.
To him it was a night of tremendous tragedy, and for the second time in his life in the numbness induced by the greater peril and the greater anxiety he failed to wince at the thought of the danger in which Oliva stood.
Indeed, analysing his sensations she seemed to him on this occasion less a victim than a fellow-worker and he found a strange comfort in that thought of partnership.
The _Megaphone_ buildings blazed with light when the car drew up to the door, messenger-boys were hurrying through the swing-doors, the two great elevators were running up and down without pause. The grey editor with a gruff voice threw over a bundle of flimsies.
"Here are the market reports," he growled, "they are not very encouraging."
Beale read them and whistled, and the editor eyed him keenly.
"Well, what do you make of it?" he asked the detective. "Wheat at a shilling a pound already. God knows what it's going to be to-morrow!"
"We have asked Germany to explain why she has prohibited the export of wheat and to give us a reason for the stocks she holds and the steps she has taken during the past two months to accumulate reserves."
"Not exactly an ultimatum. There's nothing to go to war about. The Government has mobilized the fleet and the French Government has partially mobilized her army. The question is," he said, "would war ease the situation?"
"The battle will not be fought in the field," he said, "it will be fought right here in London, in all your great towns, in Manchester, Coventry, Birmingham, Cardiff. It will be fought in New York and in a thousand townships between the Pacific and the Atlantic, and if the German scheme comes off we shall be beaten before a shot is fired."
"What does it mean?" asked the editor, "why is everybody buying wheat so frantically? There is no shortage. The harvests in the United States and Canada are good."
"There will be no harvests," said Beale solemnly; and the journalist gaped at him.
