Involuntarily my hand went out to it. It was a perfectly unconscious action on my part, and I blushed vividly when I realised what I had done. I had no authority here. I was not even known to the good man and woman before me.

The Captain, who may or may not have noted my anxiety, paid no heed either to my unfortunate self-committal or to the apologetic question with which I endeavoured to retrieve myself.

Turning to the la.s.s beside him, he handed her the slip, with the look which a man gives to a woman on whose good sense and judgment he has come to rely.

"Take it, Sally," he said. "You will know the girl if she comes in, and, what's more, you'll know how to manage the matter so as to give satisfaction to all the parties concerned. And now, sir?--" he inquired, turning towards me.

But at this instant a diversion was created by the arrival of Detective Sweet.w.a.ter, a man for whose presence I was certainly little prepared.

"The gentleman who has just gone out pa.s.sed you something," he cried, approaching the la.s.s without ceremony, though not without respect. Me he did not appear to see.

"The gentleman left a note with us for one of the poor women who sometimes straggle in here," was her quiet response. "He is interested in poor girls; tries to reclaim them."

"I am sorry," protested the detective "but I must have a glance at what he wrote. It may be of immediate importance to the police. Here is my authority," he added in lower tones, opening his coat for a moment. "You know under what suspicion the Gillespie family lies. He is a Gillespie; let me see those lines--or, stay, read them out yourself--that may be better."

The young woman hesitated, consulted the Captain with a look, then glanced down at the slip trembling in her hand. It was half unrolled, and some of its words must have met her eye.

"Why do you think this has anything to do with the serious matter you mention?" she ventured to ask.

The detective approached his mouth to her ear, but my hearing did not fail me even under these unfavourable circ.u.mstances.

"Everything has connection with it," I heard him say. "Everything they do and think. I wouldn't trust one of them round the corner. I should make the greatest mistake of my life if I allowed any secret communication written by a Gillespie to pa.s.s under my nose without an attempt to see what it was. This one may be of an innocent nature; probably is. The gentleman who left it with you pa.s.ses for a philanthropist, and as such might very readily hold communication with the worst characters in town without any other motive than the one you yourselves can best appreciate. But I must be sure of this. I have been detailed to watch his movements, and his movements have brought him here. You will therefore oblige me, Miss, if you can make it clear that the cause of justice--by which I mean the cause which I here personally represent--will not suffer injury by the free transmission of this slip to the person for whom it is meant."

"I will read you what he has written here," replied the girl. "He left it open or almost open to anyone's perusal." And I heard her read out, in low but penetrating tones, the following words:

When I last saw you, you were suffering. This is an unbearable thought to me, yet I cannot go to you for reasons which you can readily appreciate. Come to me, then. The house is always open and the servants have received orders to admit anyone who asks for me.

This was certainly warm language from a mere philanthropist to a city waif whose misery had attracted his notice. But no remarks pa.s.sed, and Sweet.w.a.ter did not seek to hinder even by a look the careful refolding of the slip and the putting of it away in the young la.s.s's desk.

Indeed, he seemed to approve of this, for the next moment I heard him say:

"That's right; take good care of the slip. If the young woman comes in, give it to her. I suppose you know her?"

"Not at all; he simply described her to us; or attempted to. She may not come in at all."

"Then keep a grip on those lines. What kind of a person did he say she was?"

"Oh, I don't know. He said she was wild-looking, but beautiful, and that she answered to some such name as Millie."

"It's likely to be a fake, the whole mess. Good-day, Captain; good-day, Miss." And Detective Sweet.w.a.ter stepped away.

I had thought him keen, yet he had paid no more attention to me than if I had been a stick. Was the corner in which I sat darker than I thought, or had he been so full of his own affairs that he failed to recognise me? I had kept my face turned away, but he a.s.suredly must have known my figure.

When he was gone the two laid their heads together for a moment, then began to bustle towards me. In the meantime I had planned a _coup d'etat_. I had considered if, by a little acting on my part, I could put them in the wrong, I might succeed in getting from them some positive facts to work upon. Accordingly, I was in a state of suppressed feeling when the Captain found himself face to face with me.

"I heard you," said I, flinging down the book I had taken up. "I have ears like a hare and I couldn't help it. I know Mr. Gillespie, and it made my blood boil to hear him addressed with suspicion. How anyone who has ever heard him speak to the poor and unfortunate could a.s.sociate him with the atrocious death of his father, I cannot imagine. So good to poor girls! So bountiful in his charities! I thought you were Christians here."

The Captain may have been a Christian, but he was also a man, and, being a man, looked nettled.

"It was a mistake for us to discuss Army affairs within reach of two such sharp ears," said he. "Mr. Gillespie has done some good work, and far be it from me to add myself to those who have a.s.sociated his name with the crime which has just made the family notorious. I simply fail to stand by him because he uses us as a cloak for his personal indulgences. He is infatuated with a woman whom he has never presumed to present to his family. This won't do for us. The other matter belongs to the police."

I allowed myself to cool down a trifle.

"I beg your pardon; you know your own business, of course. But it's a little hard for me to believe that such a refined man as Mr. Gillespie could find any other than a charitable interest in any woman likely to come straying in here. Did you ever see his home, his child, his friends?"

The Captain shrugged his shoulders and curtly replied:

"I can imagine." Then in a tone calculated to end the interview so far as this topic was concerned: "We count nothing as strange in this place, sir. We come too near the unregenerate heart. Human nature's the same, sir, in rich and in poor. And now, sir, your business? It's most time for our noon meeting, so I must ask you to be concise."

I had almost forgotten I had any business there, but I pulled myself up under his eye and told him I was on the search for a woman, too.

"But she's an old one," I made haste to a.s.sure him; "a lodging-house keeper who is in the possession of evidence of great importance to a client of mine. Her name, as told me, is Mother Merry; do you know any such person?"

He did not, but informed me that there were several queer old places down by the wharves where I might hear of her. This was enough. I had now an excuse for penetrating the district towards which I had been pointing from the first.

Thanking him, and asking his pardon for my few brusque words, I went out, and, giving my policeman a wink, turned in the direction of the river.

MILLE-FLEURS

The complications which had surrounded Leighton Gillespie were, through his own imprudence, in the way of being cleared up, though hardly to his advantage. This was not all. Either from indifference or ignorance--I hardly thought it was indifference--he had not only called attention to his own secret pa.s.sion, but laid such a trap for the object of it that she could hardly fail to fall ultimately into the hands of the police.

Under these circ.u.mstances was it my duty to proceed with the task I had imposed upon myself? Was my help needed when Mr. Gryce's right-hand man was at work? It would not seem so. But--as I was happy enough to remember before my hesitation resolved itself into action--the one clue connecting him to this murder was to be found in my hands, not theirs. I alone knew where to look for the woman who had procured him the phial of poison. This in itself created an obligation I dared not slight. I must continue my quest, if I desired to fulfil my promise to Hope Meredith.

The day was Friday and the fish-stalls were doing a lively business.

By the time I had threaded my way through innumerable sheds, I had got enough of this commodity into my nostrils to satisfy my appet.i.te for a week. I was glad when I stepped out upon the wharf.

"Is it along there you want to go?" asked the officer under whose protection I moved.

I looked, and saw fluttering before me the calico curtain which had blown in and out of Yox's story.

"Yes, if it's where an old woman named Merry is to be found."

"I'll ask."

He approached a brother officer whose presence I had not noticed, spoke to him, and came back.

"That's the place," said he. "Do you want me to go in with you?"

"Not if it's safe."

"Oh, it's safe enough at this hour. You haven't any too much cash on you, I judge? Besides, I'll hang about the door, and if you don't come out in ten minutes I'll just inquire the reason why. You see, the place's on our books and we don't want to keep too open an eye on it."

I was glad to be allowed to go in alone. I had not dared to hope for this and felt correspondingly relieved.
