〃Madame is surprised to see him; but she deals with the situation promptly。 Mason is got out of the way; a dinner basket is ordered。
We know from the conductor that he made up the berth for the first partment; that he did not go into the second partment; and that a man could quite well have been concealed from him。 So far the te would have been hidden to a marvel。 No one knows of his presence on the train except Madame; he has been careful that the maid did not see his face。 All that she could say is that he was tall and dark。 It is all most conveniently vague。 They are alone … and the train rushes through the night。 There would be no outcry; no struggle; for the man is; so she thinks; her lover。〃
He turned gently to Van Aldin。
〃Death; Monsieur; must have been almost instantaneous。 We te takes the jewel…case which lies ready to his hand。 Shortly afterwards the train draws into Lyons。〃
M。 Carrege nodded his approval。
〃Precisely。 The conductor descends。 It would be easy for our man to leave the train unseen; it would be easy to catch a train back to Paris or anywhere he pleases。 And the crime would be put down as an ordinary train robbery。 But for the letter found in Madames bag; the te would not have been mentioned。〃
〃It was an oversight on his part not to search that bag;〃 declared the missary。
〃Without doubt he thought she had destroyed that letter。 It was … pardon me; Monsieur … it was an indiscretion of the first water to keep it。〃
〃And yet;〃 murmured Poirot; 〃it was an indiscretion the te might have foreseen。〃
〃You mean?〃
〃I mean we are all agreed on one point; and that is that the te de la Roche knows one subject à fond: Women。 How was it that; knowing women as he does; he did not foresee that Madame would have kept that letter?〃
〃Yes … yes;〃 said the Examining Magistrate doubtfully; 〃there is something in what you say。 But at such times; you understand; a man is not master of himself。 He does not reason calmly。 Mon Dieu!〃 he added; with feeling; 〃if our criminals kept their heads and acted with intelligence; how should we capture them?〃
Poirot smiled to himself。
〃It seems to me a clear case;〃 said the other; 〃but a difficult one to prove。 He is a slippery customer; and unless the maid can identify him …〃
〃Which is most unlikely;〃 said Poirot。
〃True; true。〃 The Examining Magistrate rubbed his chin。 〃It is going to be difficult。〃
〃If he did indeed mit the crime …〃 began Poirot。 M。 Caux interrupted。
〃If … you say if?〃
〃Yes; Monsieur le Juge; I say if。〃
The other looked at him sharply。 〃You are right;〃 he said at last; 〃we go too fast。 It is possible that the te may have an alibi。 Then we should look foolish。〃
〃Ah; ?a par exemple;〃 replied Poirot; 〃that is of no importance whatever。 Naturally; if he mitted the crime he will have an alibi。 A man with the tes experience does not neglect to take precautions。 No; I said if for a very different reason。〃
〃And what was that?〃
Poirot wagged an emphatic forefinger。
〃The psychology。〃
〃Eh?〃 said the missary。
〃The psychology is at fault。 The te is a scoundrel … yes。 The te is a swindler … yes。 The te preys upon women … yes。 He proposes to steal Madames jewels … again yes。 Is he the kind of man to mit murder? I say no! A man of the type of the te is always a coward; he takes no risks。 He plays the safe; the mean; what the English call the lowdown game; but murder; a hundred times no!〃 He shook his head in a dissatisfied manner。
The Examining Magistrate; however; did not seem disposed to agree with him。
〃The day always es when such gentry lose their heads and go too far;〃 he observed sagely。 〃Doubtless that is the case here。 Without wishing to disagree with you; M。 Poirot …〃
〃It was only an opinion;〃 Poirot hastened to explain。 〃The case is; of course; in your hands; and you will do what seems fit to you。〃
〃I am satisfied in my own mind that the te de la Roche is the man we need to get hold of;〃 said M。 Carrege。 〃You agree with me; Monsieur le missaire?〃
〃Perfectly。〃
