Harry resumed his seat, shrugged his shoulders, and took a leisurely look at his self-possessed visitor. 'Sad and glad are contradictory terms, my friend,' said he, carelessly. 'I would rather you explained riddles than propounded them.'

'Sir Harry! Sir Harry! it is the riddle of man's life upon this earth that I am trying to explain.'

'You have set yourself a hard task, Baltic, for so far as I can see, there is no reading of that riddle.'

'Save by the light of the Gospel, sir, which makes all things plain.'

'Baltic,' said Brace, bluntly, 'there is that about you which would make me sorry to find you a Pharisee or a hypocrite. Therefore, if you please, we will stop religion and allegory, and come to plain matter-of-fact. When I knew you in Samoa, you were a sailor without a ship.'

'Add a castaway and a child of the devil, sir, and you will describe me as I was then,' burst out Baltic, in his deep voice. 'Hear me, Sir Harry, and gauge me as I should be gauged. I was, as you know, a drunken, godless, swearing dog, in the grip of Satan as fuel for hell; but when you saved my worthless life I saw that it behoved me, as it does all men, to repent. I sought out a missionary, who heard my story and set my feet in the right path. I listened to his preaching, I read the Good Book, and so learned how I could be saved. The missionary made me his fellow-labourer in the islands, and I strove to bring the poor heathen to the foot of the cross. For three years I laboured there, until it was borne in upon me that I was called upon by the Spirit to labour in the greater vineyard of London. Therefore, I came to England and looked round to see what task was fittest for my hand. On every side I saw evil prosper. The wicked, as I noted, flourished like a green bay tree; so, to bring them to repentance and punishment, I became a private inquiry agent.'

'Humph! that is a novel kind of missionary enterprise, Baltic.'

'It is a righteous one, Sir Harry. I search out iniquities; I snare the wicked man in his own nets; I make void the devices of his evil heart. If I cannot prevent crimes, I can at least punish them by bringing their doers within the grip of the law. Then when punished by man, they repent and turn to God, and thereby are saved through their own lusts.'

'Not in many cases, I am afraid. So you regard yourself as a kind of scourge for the wicked?'

'Yes! When I state that I am a missionary, I regard myself as one who works in a new way.'
