A great roar of British voices pierced the jewelled curtain of the Indian night. A toast with musical honours was being drunk in the sweltering dining-room of the officers' mess. The enthusiastic hubbub spread far, for every door and window was flung wide. Though the season was yet in its infancy, the heat was intense. Markestan had the reputation in the Indian Army for being one of the hottest corners in the Empire in more senses than one, and Kurrumpore, the military centre, had not been chosen for any especial advantages of climate. So few indeed did it possess in the eyes of Europeans that none ever went there save those whom an inexorable fate compelled. The rickety, wooden bungalows scattered about the cantonment were temporary lodgings, not abiding-places. The women of the community, like migratory birds, dwelt in them for barely four months in the year, flitting with the coming of the pitiless heat to Bhulwana, their little paradise in the Hills. But that was a twenty-four hours' journey away, and the men had to be content with an occasional week's leave from the depths of their inferno, unless, as Tommy Denvers put it, they were lucky enough to go sick, in which case their sojourn in paradise was prolonged, much to the delight of the angels.
