ot know。 He deals with the highest in Europe and with the lowest of the riff…raff of the underworld。〃
Van Aldin was looking at Poirot with suddenly awakened attention。
〃Well?〃 he demanded; a new note in his voice。
〃I ask myself;〃 said Poirot; 〃I; Hercule Poirot …〃 he thumped himself dramatically on the chest … 〃ask myself why is M。 Papopolous suddenly e to Nice?〃
Van Aldin was impressed。 For a moment he had doubted Poirot and suspected the little man of being past his job; a poseur only … now; in a moment; he switched back to his original opinion。 He looked straight at the little detective。
〃I must apologize to you; M。 Poirot。〃
Poirot waved the apology aside with an extravagant gesture。
〃Bah!〃 he cried; 〃all that is of no importance。 Now listen; M。 Van Aldin; I have news for you。〃
The millionaire looked sharply at him; all his interest aroused。
Poirot nodded。
〃It is as I say。 You will be interested。 As you know; M。 Van Aldin; the te de la Roche has been under surveillance ever since his interview with the Juge dInstruction。 The day after that; during his absence; the Villa Marina was searched by the police。〃
〃Well;〃 said Van Aldin; 〃did they find anything? I bet they didnt。〃
Poirot made him a little bow。
〃Your acumen is not at fault; M。 Van Aldin。 They found nothing of an incriminating nature。 It was not to be expected that they would。 The te de la Roche; as your expressive idiom has it; was not born on the preceding day。 He is an astute gentleman with great experience。〃
〃Well; go on;〃 growled Van Aldin。
〃It may be; of course; that the te had nothing of a promising nature to conceal。 But we must not neglect the possibility。 If then; he has something to conceal; where is it? Not in his house … the police searched thoroughly。 Not on his person; for he knows that he is liable to arrest at any minute。 There remains … his car。 As I say; he was under surveillance。 He was followed on that day to Monte Carlo。 From there he went by road to Mentone; driving himself。 His car is a very powerful one; it outdistanced his pursuers and for about a quarter of an hour they pletely lost sight of him。〃
〃And during that time you think he concealed something by the roadside?〃 asked Van Aldin; keenly interested。
〃By the roadside; no。 ?a nest pas pratique。 But listen now … me; I have made a little suggestion to M。 Carrege。 He is graciously pleased to approve of it。 In each Bureau de Poste in the neighbourhood it has been seen to that there is someone who knows the te de la Roche by sight。 Because; you see; Messieurs; the best way of hiding a thing is by sending it away by the post。〃
〃Well?〃 demanded Van Aldin; his face was keenly alight with interest and expectation。
〃Well …〃 With a dramatic flourish Poirot drew out from his pocket a loosely wrapped brown paper package from which the string had been removed。
〃During that quarter of an hours interval; our good gentleman mailed this。〃
〃The address?〃 asked the other sharply。
Poirot nodded his head。
〃Might have told us something; but unfortunately it does not。 The package was addressed to one of these little newspaper shops in Paris where letters and parcels are kept until called for on payment of a small mission。〃
〃Yes; but what is inside?〃 demanded Van Aldin impatiently。
Poirot unwrapped the brown paper and disclosed a square cardboard box。 He looked round him。
〃It is a good moment;〃 he said quietly。 〃All eyes are on the tennis。 Look; Monsieur!〃
He lifted the lid of the box for the fraction of a second。 An exclamation of utter astonishment came from the millionaire。 His face turned as white as chalk。
〃My God!〃 he breathed; 〃the rubies。〃
He sat for a minute as though dazed。 Poirot restored the box to his pocket。 Then suddenly the millionaire seemed to e out of his trance; he leaned across to Poirot and wrung his hand so heartily that the little man winced with pain。
〃This is great;〃 said Van Aldin。 〃Great! You are the goods; M。 Poirot。 Once and for all; you are the goods。〃
〃It is nothing;〃 said Poirot modestly。 〃Order; method; being prepared for eventualities beforehand … that is all there is to it。〃
〃And now; I suppose; the te de la Roche has been arrested?〃 continued Van Aldin eagerly。
〃No;〃 said Poirot。
A look of utter astonishment came over Van Aldins face。
〃But why? What more do you want?〃
〃The tes alibi is still unshaken。〃
