Henry was not much of a detective, and his human traits were
consequently highly developed. From a boy, he had never been able to
resist curiosity. If a crowd collected in the street he always added
himself to it, and he would have stopped to gape at a window with
'Watch this window' written on it, if he had been running for his life
from wild bulls. He was, and always had been, intensely desirous of
some day penetrating behind the scenes of a theatre.

And there was another thing. At last, if he accepted this invitation,
he would be able to see and speak to Alice Weston, and interfere with
the manoeuvres of the hatchet-faced man, on whom he had brooded with
suspicion and jealousy since that first morning at the station. To see
Alice! Perhaps, with eloquence, to talk her out of that ridiculous
resolve of hers!

'Why, there's something in that,' he said.

'Rather! Well, that's settled. And now, touching that sweep, who
_is_ it?'

'I can't tell you that. You see, so far as that goes, I'm just where I

might have been a failure in the matter of disguise, but nobody could
have put more quiet sinister-ness into that 'Ah!' It did much to soothe
him and ensure a peaceful night's rest.

On the following night, for the first time in his life, Henry found
himself behind the scenes of a theatre, and instantly began to
experience all the complex emotions which come to the layman in that
situation. That is to say, he felt like a cat which has strayed into a
strange hostile back-yard. He was in a new world, inhabited by weird
creatures, who flitted about in an eerie semi-darkness, like brightly
coloured animals in a cavern.

'The Girl From Brighton' was one of those exotic productions specially
designed for the Tired Business Man. It relied for a large measure of
its success on the size and appearance of its chorus, and on their
constant change of costume. Henry, as a consequence, was the centre of
a kaleidoscopic whirl of feminine loveliness, dressed to represent
such varying flora and fauna as rabbits, Parisia
