She hesitated, and glanced from her aunt's face to mine.

'June, child, I think I know what is in thy mind; I know the nature of this young man's business in this place, and you are right. If he can spare the time, it is right that we should know, if possible, what we have to guard against, to fear or avoid. Is it thy pleasure, sir, to undertake this for us?'

I turned silently toward Miss Jenrys.

'Aunt Ann is right,' she said, with decision. 'Can you take this matter in hand?'

'I will take it in hand,' I replied. 'But tell me just what you wish. Do you simply want insured protection against annoyance, or do you want this brunette followed up until we learn why she has singled you out for her peculiar attentions?'

'I have heard it said,' Miss Jenrys replied, 'that the detective fever is contagious, and I feel now as if I must have this little mystery unravelled. I dare say it will end in something stupid and commonplace. Still, let us unravel it if possible. What say you, Aunt Ann?'

'I have already told thee that I detest mysteries. Yes, we must know what it means.'

'And know you shall,' I declared, 'if it rests within my power.'

The sun was fast travelling toward the zenith, and I had promised Dave a rendezvous at noon.

It was not difficult to impress upon these two clever women the need for perfect secrecy, and that no one must guess at the truth concerning myself. I had observed that Monsieur Voisin addressed me as Mr. Masseys, and that Miss Jenrys had spoken my name in performing the introduction very indistinctly, and before I left she spoke of this.
