"What I mean is this," he continued, in reply to Purchase's glance of inquiry.  "The poor old _Psyche_, as we all know, was a phenomenally slow ship, yet her successes, since she came on the Coast, have been greater and more brilliant than those of any other vessel belonging to the squadron.  And why?  Because she had a trick of always turning up on the right spot at the right moment.  Now it seems to me that this peculiarity of hers can scarcely have escaped the notice of the slave- trading fraternity, because it was so very marked.  I imagine that they must often have wondered by what means we gained our information; and when at length the thing had become so unmistakable as to provoke both conjecture and discussion it would not take them long to arrive at a very shrewd suspicion of the truth.  When once the matter had reached this stage discovery could not possibly be very long delayed.  Captain Harrison was undoubtedly a well-known figure in Sierra Leone; he was of so striking a personality that it could not be otherwise, and I am of opinion that at length his disguise was penetrated.  He was recognised in one of those flash places in Freetown that are especially patronised by individuals of shady and doubtful character; and a scheme was devised for his and our undoing which has succeeded only too well.  In a word, I believe that the whole of the information upon which he acted when arranging this most unfortunate expedition was carefully fabricated for the express purpose of bringing about the destruction of the ship, and was confided to him by some one who had recognised him as her captain. I believe, Purchase, that you were cut adrift last night, either by the individual who spun the yarn, or by some emissary or emissaries of his who have a lurking-place somewhere in this neighbourhood; and, if the truth could be got at, I believe it would be found that the schooner which we saw come out of this river on the day before yesterday--and which the captain was led to believe was a decoy intended to draw us off the coast--was actually chock-full of slaves!"
