'I have need of your services, Monsieur Gerard,' said he. 'I may be safer with a good sword at my side, and there are reasons why yours should be the one which I select. But first of all I must bind you to secrecy. Whilst I live what passes between us today must be known to none but ourselves.'

I thought of Talleyrand and of Lasalle, but I promised.

'In the next place, I do not want your opinions or conjectures, and I wish you to do exactly what you are told.'

I bowed.

'It is your sword that I need, and not your brains. I will do the thinking. Is that clear to you?'

'Yes, sire.'

'You know the Chancellor's Grove, in the forest?'

I bowed.

'You know also the large double fir-tree where the hounds assembled on Tuesday?'

Had he known that I met a girl under it three times a week, he would not have asked me. I bowed once more without remark.
