wondered where Mrs. Oliver was.
Footsteps behind him made him turn his head. A young man was coming up the path from the quay; a very dark young man, faultlessly attired in yachting costume. He paused as though disconcerted by the scene before him.
Then he spoke hesitatingly to Poirot.
âYou will excuse me. Is this the house of Sir George Stubbs?â
âIt is indeed.â Poirot paused and then hazarded a guess. âAre you, perhaps, the cousin of Lady Stubbs?â
âI am Etienne de Sousaââ
âMy name is Hercule Poirot.â
They bowed to each other. Poirot explained the circumstances of the fête. As he finished, Sir George came across the lawn towards them from the coconut shy.
âDe Sousa? Delighted to see you. Hattie got your letter this morning. Whereâs your yacht?â
âIt is moored at Helmmouth. I came up the river to the quay here in my launch.â
âWe must find Hattie. Sheâs somewhere aboutâ¦Youâll dine with us this evening, I hope?â
âYou are most kind.â
âCan we put you up?â
âThat also is most kind, but I will sleep on my yacht. It is easier so.â
âAre you staying here long?â
âTwo or three days, perhaps. It depends.â De Sousa shrugged elegant shoulders.
âHattie will be delighted, Iâm sure,â said Sir George politely. âWhere is she? I saw her not long ago.â
He looked round in a perplexed manner.
âShe ought to be judging the childrenâs fancy dress. I canât understand it. Excuse me a moment. Iâll ask Miss Brewis.â
He hurried off. De Sousa looked after him. Poirot looked at de Sousa.
âIt is some little time since you last saw your cousin?â he asked.
The other shrugged his shoulders.
âI have not seen her since she was fifteen years old. Soon after that she was sent abroadâto school at a convent in France. As a child she promised to have good looks.â
He looked inquiringly at Poirot.
âShe is a beautiful woman,â said Poirot.
âAnd that is her husband? He seems what they call âa good fellow,â but not perhaps very polished? Still, for Hattie it might be perhaps a little difficult to find a suitable husband.â
Poirot remained with a politely inquiring expression on his face. The other laughed.
âOh, it is no secret. At fifteen Hattie was mentally undeveloped. Feebleminded, do you not call it? She is still the same?â
âIt would seem soâyes,â said Poirot cautiously.
De Sousa shrugged his shoulders.
âAh, well! Why should one ask it of womenâthat they should be intelligent? It is not necessary.â
Sir George was back, fuming. Miss Brewis was with him, speaking rather breathlessly.
âIâve no idea where she is, Sir George. I saw her over by the fortune tellerâs tent last. But that was at least twenty minutes or half an hour ago. Sheâs not in the house.â
âIs it not possible,â asked Poirot, âthat she has gone to observe the progress of Mrs. Oliverâs murder hunt?â
Sir Georgeâs brow cleared.
âThatâs probably it. Look here, I canât leave the shows here. Iâm in charge. And Amandaâs got her hands full. Could you possibly have a look round, Poirot? You know the course.â
But Poirot did not know the course. However, an inquiry of Miss Brewis gave him rough guidance. Miss Brewis took briskcharge of de Sousa and Poirot went off murmuring to himself, like an incantation: âTennis Court, Camellia Garden, The Folly, Upper Nursery Garden, Boathouseâ¦.â
As he passed the coconut shy he was amused to notice Sir George proffering wooden balls with a dazzling smile of welcome to the same young Italian woman whom he had driven off that morning and who was clearly puzzled at his change of attitude.
He went on his way to the tennis court. But there was no one there but
