Feeling the importance of not interrupting Sergeant Cuff's examination of the boy, I received the clerk in another room.
He came with bad news of his employer.
The agitation and excitement of the last two days had proved too much for Mr. Bruff.
He had awoke that morning with an attack of gout; he was confined to his room at Hampstead; and, in the present critical condition of our affairs, he was very uneasy at being compelled to leave me without the advice and assistance of an experienced person.
The chief clerk had received orders to hold himself at my disposal, and was willing to do his best to replace Mr. Bruff.
I wrote at once to quiet the old gentleman's mind, by telling him of Sergeant Cuff's visit: adding that Gooseberry was at that moment under examination; and promising to inform Mr. Bruff, either personally, or by letter, of whatever might occur later in the day.
Having despatched the clerk to Hampstead with my note, I returned to the room which I had left, and found Sergeant Cuff at the fireplace, in the act of ringing the bell.
"I beg your pardon, Mr. Blake," said the Sergeant. "I was just going to send word by your servant that I wanted to speak to you.
There isn't a doubt on my mind that this boy--this most meritorious boy," added the Sergeant, patting Gooseberry on the head, "has followed the right man.
Precious time has been lost, sir, through your unfortunately not being at home at half past ten last night.
The only thing to do, now, is to send for a cab immediately."
In five minutes more, Sergeant Cuff and I (with Gooseberry on the box to guide the driver) were on our way eastward, towards the City.
"One of these days," said the Sergeant, pointing through the front window of the cab, "that boy will do great things in my late profession.
He is the brightest and cleverest little chap I have met with, for many a long year past.
You shall hear the substance, Mr. Blake, of what he told me while you were out of the room.
You were present, I think, when he mentioned that he held on behind the cab, and ran after it?"
"Yes."
"Well, sir, the cab went from Lombard Street to the Tower Wharf.
The sailor with the black beard got out, and spoke to the steward of the Rotterdam steamboat, which was to start next morning.
He asked if he could be allowed to go on board at once, and sleep in his berth over-night.
The steward said, No.
The cabins, and berths, and bedding were all to have a thorough cleaning that evening, and no passenger could be allowed to come on board, before the morning.
The sailor turned round, and left the wharf.
When he got into the street again, the boy noticed for the first time, a man dressed like a respectable mechanic, walking on the opposite side of the road, and apparently keeping the sailor in view.
The sailor stopped at an eating-house in the neighbourhood, and went in.
The boy--not being able to make up his mind, at the moment--hung about among some other boys, staring at the good things in the eating-house window.
He noticed the mechanic waiting, as he himself was waiting--but still on the opposite side of the street.
After a minute, a cab came by slowly, and stopped where the mechanic was standing.
The boy could only see plainly one person in the cab, who leaned forward at the window to speak to the mechanic.
He described that person, Mr. Blake, without any prompting from me, as having a dark face, like the face of an Indian."
It was plain, by this time, that Mr. Bruff and I had made another mistake.
The sailor with the black beard was clearly not a spy in the service of the Indian conspiracy.
Was he, by any possibility, the man who had got the Diamond?
"After a little," pursued the Sergeant, "the cab moved on slowly down the street.
The mechanic crossed the road, and went into the eating-house.
The boy waited outside till he was hungry and tired--and then went into the eating-house, in his turn.
He had a shilling in his pocket; and he dined sumptuously, he tells me, on a black-pudding, an eel-pie, and a bottle of ginger-beer.
What can a boy not digest?
The substance in question has never been found yet."
"What did he see in the eating-house?" I asked.
"Well, Mr. Blake, he saw the sailor reading the newspaper at one table, and the mechanic reading the newspaper at another.
It was dusk before the sailor got up, and left the place.
He looked about him suspiciously when he got out into the street.
The boy--BEING a boy--passed unnoticed.
The mechanic had not come out yet.
The sailor walked on, looking about him, and apparently not very certain of where he was going next.
The mechanic appeared once more, on the opposite side of the road.
The sailor went on, till he got to Shore Lane, leading into Lower Thames Street.
There he stopped before a public-house, under the sign of
'The Wheel of Fortune,' and, after examining the place outside, went in.
