Inexplicably, he again seemed to be in some sort of distress. ‘It has, in fact,’ he said, ‘a continental flavour. But for those who have ears to hear and eyes to see, it has a wider implication than I have suggested. It is a tale, in point of fact, about the struggle of the human being in the detestable situation in which from the beginning he has found himself. Now I descend.’ He climbed down his step-ladder, groaning lamentably. ‘And now,’ he said, ‘we have some light and we see if what I have done is good. Go out into the front of the house and in a moment I join you.’

By the time Martyn reached the sixth row of the stalls the stage was fully illuminated, and for the first time she saw the set for Act II as Jacko had intended it.

It was an interior, simple in design and execution, but with an air of being over-civilized and stale. ‘They are,’ Jacko explained, slumping into a seat beside her, ‘bad people who live in it. They are not bad of their own volition, but because they have been set down in this place by their heredity and cannot escape. And now you say, all this is pretentious nonsense, and nobody will notice my set except perhaps a few queers who come to first nights and in any case will get it all wrong. And now we wash ourselves and go out to a place where I am known, and we eat a little, and you tell me why you look like a puppy who has found his tail but dare not wag it. Come.’

The restaurant where Jacko was known turned out to be hard by the theatre, and situated in a basement. He insisted on paying for a surprisingly good meal, and Martyn’s two and fourpence remained in her pocket. Whereas the curiosity of Fred Badger and Bob Cringle, and in some degree of the actors, had been covert and indirect, Jacko’s was unblushing and persistent.

‘Now,’ he said, over their coffee, ‘I ask you my questions. If there is a secret you tell me so, and with difficulty I shut myself up. If not, you confide in me, because everybody in the Vulcan makes me their confidant and I am greatly flattered by this. In any case we remain friends, no bones broken, and we repeat our little outings. How old do you think I am?’

With some embarrassment, Martyn looked at his scrawny neck, at the thin lichen-like growth of fuzz on his head, and at his heavily scored and indented face. ‘Fifty-seven,’ she ventured.
