The “detective” chapter mentioned in this letter was not included in ‘A Tramp Abroad.’  It was published separately, as ’The Stolen White Elephant’ in a volume bearing that title.  The play, which he had now found “dreadfully witless and flat,” was no other than “Simon Wheeler, Detective,” which he had once regarded so highly.  The “Stewart” referred to was the millionaire merchant, A. T. Stewart, whose body was stolen in the expectation of reward.

To W. D. Howells, in Boston: 

Munich, Jan. 21, (1879) My dear Howells,—­It’s no use, your letter miscarried in some way and is lost.  The consul has made a thorough search and says he has not been able to trace it.  It is unaccountable, for all the letters I did not want arrived without a single grateful failure.  Well, I have read-up, now, as far as you have got, that is, to where there’s a storm at sea approaching,—­and we three think you are clear, out-Howellsing Howells.  If your literature has not struck perfection now we are not able to see what is lacking.  It is all such truth—­truth to the life; every where your pen falls it leaves a photograph.  I did imagine that everything had been said about life at sea that could be said, but no matter, it was all a failure and lies, nothing but lies with a thin varnish of fact,—­only you have stated it as it absolutely is.  And only you see people and their ways, and their insides and outsides as they are, and make them talk as they do talk.  I think you are the very greatest artist in these tremendous mysteries that ever lived.  There doesn’t seem to be anything that can be concealed from your awful all-seeing eye.  It must be a cheerful thing for one to live with you and be aware that you are going up and down in him like another conscience all the time.  Possibly you will not be a fully accepted classic until you have been dead a hundred years,—­it is the fate of the Shakespeares and of all genuine prophets, —­but then your books will be as common as Bibles, I believe.  You’re not a weed, but an oak; not a summer-house, but a cathedral.  In that day I shall still be in the Cyclopedias, too, thus:  “Mark Twain; history and occupation unknown—­but he was personally acquainted with Howells.”  There—­I could sing your praises all day, and feel and believe every bit of it.

My book is half finished; I wish to heaven it was done.  I have given up writing a detective novel—­can’t write a novel, for I lack the faculty; but when the detectives were nosing around after Stewart’s loud remains, I threw a chapter into my present book in which I have very extravagantly burlesqued the detective business—­if it is possible to burlesque that business extravagantly.  You know I was going to send you that detective play, so that you could re-write it.  Well I didn’t do it because I couldn’t find a single idea in it that could be useful to you.  It was dreadfully witless and flat.  I knew it would sadden you and unfit you for work.
