‘In the dining-room, too. But take no notice whatever of me.’

‘Well, it’s a daft-like sort of proceeding, any way; but I’ll do it.’

Then, having procured some golf-balls, he addressed himself to Chunda in Hindustani, and in a few moments they went together into the dining-room.

Brodie followed shortly after, and, taking a book from a little shelf that hung on the wall, he threw himself on to a lounge and appeared to be reading.

In a short while Jarvis took the balls from his pocket, and, saying something to Chunda, who sat on a chair by the window, he threw one ball after another at him, and the native held forth his hands to catch them; but, not being in a playful humour, he did not cast the balls back, but very soon got up and went out, looking very much annoyed.

‘Well, what does that tomfoolery mean?’ asked Jarvis.

‘A good deal to me. I’ve learnt a startling fact by it.’

The skipper would have been glad to have had an explanation, for naturally his curiosity was greatly aroused, and he couldn’t conceive what the ball-throwing could possibly have indicated. But Brodie resolutely refused to satisfy him.

‘You have rendered me a service,’ he said. ‘Now, that’s enough for the present. If I succeed in fitting the pieces of this strange puzzle together, you shall know what my motive was. Rest assured I do nothing without a motive. But I am going to exact a further service from you now. I want you to stay here all night, as I myself intend to stay. Chunda talked of leaving to-morrow. He must not leave, and, if necessary, you must find some means of detaining him.’

‘Do you mean to say you suspect Chunda of having committed the crime?’—his amazement growing.
