ector ran it through hurriedly。 The paper was stamped American Embassy；' and it was the digest of several opinions as to the effect of the new patent law upon the import of articles manufactured under processes controlled by the Coulson & Bruce syndicate。 At the end there were a few lines in the Ambassador's own handwriting； summing up the situation。 Mr。 Coulson produced another packet of letters and documents。
〃If you've an hour or so to spare； Mr。 Jacks；〃 he said； 〃I'd like to go right into this with you； if it would interest you any。 It's my business over here； so naturally I am glad enough of an opportunity to talk it over。〃
Mr。 Jacks passed back the paper promptly。
〃I am extremely obliged to you；〃 he said。 〃I am sure I should find it most interesting。 Another time I should be very glad indeed to look through those specifications； but just now I have this affair of my own rather on my mind。 About this Mr。 Richard Vanderpole； Mr。 Coulson； then；〃 he added。 〃Do I understand that this young man came to you as a complete stranger？〃
〃Absolutely；〃 Mr。 Coulson answered。 〃I never saw him before in my life。 As decent a young chap as ever I met with； all the same；〃 he went on； 〃and comes of a good American stock； too。 They tell me there's going to be an inquest and that I shall be summoned； but I know nothing more than what I've told you。 If I did； you'd be welcome to it。〃
Mr。 Jacks leaned back in his chair。 Certainly the situation increased in perplexity！ The man by his side was talking now of the adaptation of one of his patents to some existing machinery； and Jacks watched him covertly。 He considered himself； to some extent； a physiognomist。 He told himself it was not possible that this man was playing a part。 Mr。 James B。 Coulson sat there； the absolute incarnation of the genial man of affairs； interested in his business； interested in the great subject of dollar…getting； content with himself and his position；a person apparently of little imagination； for the shock of this matter concerning which they had been talking had already passed away。 He was doing his best to explain with a pencil on the back of an illustrated paper some new system of wool…bleaching。
〃Mr。 Coulson；〃 the Inspector said suddenly； 〃do you know a young lady named Miss Penelope Morse？〃
It was here； perhaps； that Mr。 Coulson sank a little from the heights of complete success。 He repeated the name； and obviously took time to think before he answered。
〃Miss Penelope Morse；〃 the Inspector continued。 〃She is a young American lady； who lives with an invalid aunt in Park Lane； and who is taken everywhere by the Duchess of Devenham； another aunt； I believe。〃
〃I suppose I may say that I am acquainted with her；〃 Mr。 Coulson admitted。 〃She came here the other evening with a young manSir Charles Somerfield。〃
〃Ah！〃 the Inspector murmured。
〃She'd read that interview of mine with the Comet man；〃 Mr。 Coulson said； 〃and she fancied that perhaps I could tell her something about Hamilton Fynes。〃
〃First time you'd met her； I suppose？〃 the Inspector remarked。
〃Sure！〃 Mr。 Coulson answered。 〃As a matter of fact； I know very few of my compatriots over here。 I am an American citizen myself； and I haven't too much sympathy with any one； man or woman； who doesn't find America good enough for them to live in。〃
The Inspector nodded。
〃Quite so；〃 he agreed。 〃So you hadn't anything to tell this young lady？〃
〃Not a thing that she hadn't read in the Comet；〃 Mr。 Coulson replied。 〃What brought her into your mind； anyway？〃
〃Nothing particular；〃 the Inspector answered carelessly。 〃Well； Mr。 Coulson； I won't take up any more of your time。 I am convinced that you have told me all that you know； and I am afraid that I shall have to look elsewhere to find the loose end of this little tangle。〃
〃Stay and have another drink；〃 Mr。 Coulson begged。 〃I've nothing to do。 There are one or two boys coming in later who'll like to meet you。〃
The Inspector shook his head。
〃I must be off；〃 he said。 〃I want to get into my office before six o'clock。 I dare say I shall be running across you again before you go back。〃
He shook hands and turned away。 Then Mr。 Coulson made what was； perhaps； his second slight mistake。
〃Say； Mr。 Jacks；〃 he exclaimed； 〃what made you mention that young lady's name； anyway？ I'm curious to know。〃
The Inspector looked thoughtfully at the end of the fresh cigar which he had just lit。
〃Well；〃 he said； 〃I don't know that there was anything definite in my mind； only it seems a little strange that you and Miss Penelope Morse should both have been acquainted with the murdered man and that you should have come across one another。〃
〃Sort of bond between us； eh？〃 Mr。 Coulson replied。 〃She seemed a very charming young lady。 Cut above Fynes； I should think。〃
The detective smiled。
〃All your American young ladies who come over here are charming；〃 he said。 〃Goodbye； Mr。 Coulson； and many thanks！〃
The Inspector passed out； and the man whom he had come to visit； after a moment's hesitation； resumed his seat。
〃These aren't American methods；〃 he muttered to himself。 〃I don't understand them。 That man Jacks is either a simpleton or he is too cunning for me。〃
He crossed to a writing table and scribbled an unnecessary note； addressing it to a firm in the city。 Then he rang for a messenger boy and handed it to him for delivery。 A few minutes afterwards he strolled out into the hall。 The boy was in the act of handing the note to one of the head porters； who carefully copied the address。 Mr。 Coulson returned to the smoking room； whistling softly to himself。
CHAPTER XI。 A COMMISSION
Mr。 Robert Blaine…Harvey； American Ambassador and Plenipotentiary Extraordinary to England； was a man of great culture； surprising personal gifts； and with a diplomatic instinct which amounted almost to genius。 And yet there were times when he was puzzled。 For at least half an hour he had been sitting in his great library； looking across the Park； and trying to make up his mind on a very important matter。 It seemed to him that he was face to face with what amounted almost to a crisis in his career。 His two years at the Court of St。 James had been pleasant and uneventful enough。 The small questions which had presented themselves for adjustment between the two countries were； after all； of no particular importance and were easily arranged。 The days seemed to have gone by for that over…strained sensitiveness which was continually giving rise to senseless bickerings； when every trilling breeze seemed to fan the smouldering fires of jealousy。 The two great English…speaking nations appeared finally to have realized the absolute folly of continual disputes between countries whose destiny and ideals were so completely in accord and whose interests were； in the main； identical。 A period of absolute friendliness had ensued。 And now there had come this little cloud。 It was small enough at present； but Mr。 Harvey was not the one to overlook its sinister possibilities。 Two citizens of his country had been barbarously murdered within the space of a few hours； one in the heart of the most thickly populated capital in the world； and there was a certain significance attached to this fact which the Ambassador himself and those others at Washington perfectly well realized。 He glanced once more at the most recent letter on the top of this pile of correspondence and away again out into the Park。 It was a difficult matter； this。 His friends at Washington did not cultivate the art of obscurity in the words which they used； and it had been suggested to him in black and white that the murder of these two men； under the particular circumstances existing； was a matter concerning which he should speak very plainly indeed to certain August personages。 Mr。 Harvey； who was a born diplomatist； understood the difficulties of such a proceeding a good deal more than those who had propounded it。
There was a knock at the door； and a footman entered； ushering in a visitor。
〃The young lady whom you were expecting； sir；〃 he announced discreetly。
Mr。 Harvey rose at once to his feet。
〃My dear Penelope；〃 he said； shaking hands with her； 〃this is charming of you。〃
Penelope smiled。
〃It seems quite like old times to feel myself at home here once more；〃 she declared。
Mr。 Harvey did not pursue the subject。 He was perfectly well aware that Penelope； who had been his first wife's greatest friend； had never altogether forgiven him for his somewhat brief period of mourning。 He drew an easy chair up to the side of his desk and placed a footstool for her。
〃I should not have sent for you；〃 he said； 〃but I am really and honestly in a dilemma。 Do you know that； apart from endless cables； Washington has favored me with one hundred and forty pages of foolscap all about the events of the week before last？〃
Penelope shivered a little。
〃Poor Dicky！〃 she murmured； looking away into the fire。 〃And to think that it was I who sent him to his death！〃
Mr。 Harvey shook his head。
〃No；〃 he said； 〃I do not think that you need reproach yourself with that。 As a matter of fact； I think that I should have sent Dicky in any case。 He is not so well known as the others； or rather he wasn't associ
