A review in The Times notes:

The setting–big business in Australia–is exotic enough to inspire immediate interest. The situation–an electronics expert up against it because his employers have found out his background and want his resignation or a guarantee that he will be 'sensible'–should give rise to some gripping drama, especially in the inevitable board room confrontations.

And so it did, despite too many awful lines (cliché and whimsy) which an efficient editorial blue pencil would have removed. The character of the chairman of the board was credibly ruthless and practical, and the hero, cussed, always ready (even eager) to stick his neck out, but basically weak, an obvious case of a martyr complex, was maddening but believable.
