'Yes, do; and, I say, you'll lay hands on that man of Hawke's easily enough in a day or two.'

'Oh, certainly,' said Polycarp. 'I have not forgotten him. But I was compelled to deal with you first.'

Twisting his white moustache, and buttoning his overcoat across the vast acreage of his shirt-front, Polycarp disappeared from Hugo's view into the corridor.


CHAPTER XVIII

HUSBAND AND WIFE

Hugo bolted the front-door on the inside, relighted the candle which Hawke's man had used as a weapon, and placed it in the middle of the hall floor. He then penetrated into the servants' part of the flat, and emerged on to the balcony by the small side-door, which was open, and had evidently been forced by Hawke's man. And there, on the balcony, he leaned over the balustrade in the cold humid night, and tried to recover his calmness. He felt that any systematic, scientific search of the premises would be impossible to him until his mind resembled somewhat less a sea across which a hurricane has just passed.

Many questions stood ready to puzzle his brain, but he ignored them all, and fell into a vague reverie, of which Camilla was the centre. And from this reverie he was suddenly startled by the clear, unmistakable sound of a door being shut within the flat. It was not the shutting of a door by the wind, but the careful, precise shutting of a door by some person who had a habit of shutting doors as doors ought to be shut.

'Polycarp has returned!' was his first thought. But he remembered. 'No! I bolted the front-door on the inside.'

The conundrum of the clock and of the two sizes of footprints in the drawing-room recurred to him. Without allowing himself to hesitate, he strode back again into the flat, with a sort of unbreathed sigh, an unuttered complaint against circumstances for not giving him an instant's peace.
