‘I to England come for two week holiday. I come from Holland. I like England very much. I have been Stratford Avon, Shakespeare Theatre and Warwick Castle. Then I have been Clovelly, now I have seen Exeter Cathedral and Torquay – very nice – I come to famous beauty spot here and tomorrow I cross river, go to Plymouth where discovery of New World was made from Plymouth Hoe.’

‘And you, signorina?’ Poirot turned to the other girl. But she only smiled and shook her curls.

‘She does not much English speak,’ said the Dutch girl kindly. ‘We both a little French speak – so we talk in train. She is coming from near Milan and has relative in England married to gentleman who keeps shop for much groceries. She has come with friend to Exeter yesterday, but friend has eat veal ham pie not good from shop in Exeter and has to stay there sick. It is not good in hot weather, the veal ham pie.’

At this point the chauffeur slowed down where the road forked. The girls got out, uttered thanks in two languages and proceeded up the left-hand road. The chauffeur laid aside for a moment his Olympian aloofness and said feelingly to Poirot:

‘It’s not only veal and ham pie – you want to be careful of Cornish pasties too. Put anything in a pasty they will, holiday time!’

He restarted the car and drove down the right-hand road which shortly afterwards passed into thick woods. He proceeded to give a final verdict on the occupants of Hoodown Park Youth Hostel.

‘Nice enough young women, some of ’em, at that hostel,’ he said; ‘but it’s hard to get them to understand about trespassing. Absolutely shocking the way they trespass. Don’t seem to understand that a gentleman’s place is private here. Always coming through our woods, they are, and pretending that they don’t understand what you say to them.’ He shook his head darkly.

They went on, down a steep hill through woods, then through big iron gates, and along a drive, winding up finally in front of a big white Georgian house looking out over the river.

The chauffeur opened the door of the car as a tall black-haired butler appeared on the steps.

‘Mr Hercule Poirot?’ murmured the latter.

‘Yes.’

‘Mrs Oliver is expecting you, sir. You will find her down at the Battery. Allow me to show you the way.’

Poirot was directed to a winding path that led along the wood with glimpses of the river below. The path descended gradually until it came out at last on an open space, round in shape, with a low battlemented parapet. On the parapet Mrs Oliver was sitting.

She rose to meet him and several apples fell from her lap and rolled in all directions. Apples seemed to be an inescapable motif of meeting Mrs Oliver.
