Murgatroyd directed a menacing glance at him.

'You'd better stay where you belong,' he said, in his thick, growling voice. 'There's things in this house that don't want seeing.'

'Ah!' agreed the cook, dropping an onion in the cauldron.

Wilfred could not repress a shudder.

But, even as he shuddered, he was conscious of a certain relief. At least, he reflected, they were not starving his darling. That cutlet had smelt uncommonly good: and, if the bill of fare was always maintained at this level, she had nothing to complain of in the catering.

But his relief was short-lived. What, after all, he asked himself, are cutlets to a girl who is imprisoned in a locked room of a sinister country-house and is being forced to marry a man she does not love? Practically nothing. When the heart is sick, cutlets merely alleviate, they do not cure. Fiercely Wilfred told himself that, come what might, few days should pass before he found the key to that locked door and bore away his love to freedom and happiness.

The only obstacle in the way of this scheme was that it was plainly going to be a matter of the greatest difficulty to find the key. That night, when his employer dined, Wilfred searched his room thoroughly. He found nothing. The key, he was forced to conclude, was kept on the baronet's person.

Then how to secure it?

It is not too much to say that Wilfred Mulliner was nonplussed. The brain which had electrified the world of Science by discovering that if you mixed a stiffish oxygen and potassium and added a splash of trinitrotoluol and a spot of old brandy you got something that could be sold in America as champagne at a hundred and fifty dollars the case had to confess itself baffled.
