‘Oh yes, I’m sure about that part of the business. It was conspicuous enough.’

When Brodie parted from the skipper, he felt that he had struck a trail, although he could not make much of it just then. But it will readily be gathered that he had begun to suspect Chunda of having committed the crime.

It was difficult to understand why Chunda should have burnt his gown or jacket unless it was to destroy traces of guilt. If there was blood on his jacket, and it was the blood of one of the victims, he would know that it might prove a ghastly piece of evidence if detected; and so he had committed it to the flames as the most effectual means of getting rid of it.

Now, assuming this surmise of Brodie’s was correct, it was obvious that it was not Maggie Stiven’s blood, because the nature of the wound that brought about her death was such that there was only very little outward bleeding. But if Balfour, when he went upstairs to ascertain the cause of the scream, was suddenly attacked and stabbed to death by the native, was it not reasonable to suppose that he bled so profusely as to dye the garments of his murderer?

This chain of reasoning threw a new light on the affair, and Brodie, who had made up his mind that he would read the riddle if it could be read, returned once more to Corbie Hall. He learnt that Chunda had been back about half an hour, and had given the other servants to understand that he was ill and half frozen, and was going to bed. Whereupon the detective furnished himself with a lamp, and proceeded to carefully examine the stair carpet and the landings for suggestive stains, but saw nothing that aroused his suspicions. As he could not talk to Chunda, he did not disturb him, but the next morning, quite early, he went down to the Hall again in company with Jarvis.

Chunda told the skipper, in answer to questions put to him, that he had not gone out on the previous day to attend the funeral, as stated, but to make arrangements for taking his departure from the country. He could not endure the climate; it made him very ill. Besides that, he felt that he would go mad if he stayed there, for there wasn’t a soul he could talk to, and his loneliness was terrible. He therefore intended to start on the following day for Southampton, and two days later would sail in a P. and O. steamer for India.

All that he had said seemed very feasible, and that he was ill and did suffer from the cold was evident.

Nevertheless, Brodie’s suspicions were not allayed. It was not easy to allay them when once they were thoroughly aroused; and having reasoned the case out from every possible point of view, he had come to the conclusion that Chunda was in a position to let in light where there was now darkness if he chose to speak. That is to say, he knew something of the crime, though, of course, at this stage there wasn’t a scrap of evidence against the native that would have justified his arrest. Moreover, Brodie found himself confronted with a huge difficulty in the way of making his theory fit in. If Chunda had really murdered Balfour, how had he managed to dispose of the body? That question was certainly a poser, and no reasonable answer could be given to it.

It must not be forgotten that, from the moment of the scream being first heard to the discovery of Maggie Stiven’s body on the mat at the foot of the stairs, not more than half an hour at the outside had elapsed. In that brief space of time Balfour had been so effectually got rid of that there was not a trace of him. It was bewildering to try and understand how that disappearance had been accomplished, unless it was with the aid of some devilish art and unholy magic. But as Brodie had no belief in that kind of thing, he was convinced that, sooner or later, what was then an impenetrable mystery would be explained by perfectly rational, though probably startling, causes. Be that as it might, having got his fangs fixed, to use a figure of speech, he held on with bulldog tenacity, and he was not disposed to exonerate Chunda until he felt convinced that his suspicions were unfounded.

‘Do you know, captain, if there are any balls of any kind in the house?’ he asked abruptly of Jarvis, who looked at him with some astonishment, for the question seemed so irrelevant and out of place.
