HD 149240, an object discussed inconclusively and in part erroneously in two previous papers in this series, is shown to be a triple system with two components (probably both late-type dwarfs) visible in the spectrum. The primary star is the singleton in the outer orbit, the period of which has already been established as 1040 d; its companion is now shown to be a single-lined binary system with a 51-d period, and a model for the system is proposed.
