When did Harrison mention to Lathom his intention of gathering Amanita rubescens? This question is important, because, if the poisonous fungi were introduced among the harmless ones in their natural state, it is absolutely necessary that the two varieties should bear at least a superficial resemblance to one another. Even in a half-cooked state, there could be no confusion between Amanita muscaria and, say, Chantarelles or Bolitus edulis or Amanitopris fulva. Unfortunately, no one can throw any light on this except Lathom himself, and it is not likely that he will tell the truth.
Note: To verify the habitat of Amanita rubescens, and, if possible, its presence in the actual dish of fungi analysed.
C. Further Questions and Objections (Miscellaneous)
If Lathom was guilty of administering poison to Harrison why did he return to ‘The Shack’ on Saturday? Would it not have been wiser to remain in town till the death was discovered?
This is an objection which to me appears to carry some weight. I can, however, see certain considerations which might account for a proceeding so apparently reckless from a practical point of view.
(a) Lathom may have wished to be on the spot to conceal any accidental traces of the crime. As we do not yet know his exact procedure, it is not certain what these could have been — a bottle, perhaps, containing extract of Amanita muscaria, a pan in which he had prepared it; a book or papers containing notes; traces of his previous arrival by motorbicycle or otherwise; possibly some letter or message left by Harrison, containing his own suspicions as to the manner of his death.
Note: Munting’s opinion is that Lathom originally intended to remain alone in ‘The Shack’ while he (Munting) went to fetch help, but when it came to the point found himself unable to face it. This is consistent with the above explanation, if we suppose that Lathom was overcome by fear or remorse at the sight of the body, and was thus prevented from carrying out his design. From Munting’s own statement it will be seen that Lathom was in a nervous state from the moment of his meeting Munting in town, down to the time when the body was discovered.
(b) Supposing the plot had failed to work, Harrison would have been expecting Lathom’s return. Let us say he had discovered an Amanita muscaria among his fungi — he would wonder how it had got there, and if Lathom never turned up might conceive such suspicion of him as would put him on his guard against any further attempts. On the other hand, he might have mentioned to people in the neighbourhood that Lathom was due to come back, in which case, the plot succeeding, Lathom’s absence might have a suspicious look.
Further explanations suggested by the Muntings:
(c) Lathom (supposing him guilty) would probably have no idea when the death might be expected to take place. As Thursday, Friday and Saturday passed without news, he might be overcome by nervous restlessness and an overwhelming anxiety to see for himself what was going on. (I suppose that from artists and persons of unbalanced temperament, such behaviour may be expected, half-witted as it may appear.)
(d) The alleged hankering of a murderer to revisit the scene of the crime. (This I hold to be pure superstition and quite baseless in fact.)
(e) Remorse. Perhaps Lathom regretted what he had done, and was making a belated effort to save Harrison’s life by fetching medical assistance before it was too late. (In this suggestion, put forward by Mrs Munting, the wish is probably father to the thought.)
Why did Lathom take Munting down to ‘The Shack’ with him? This again seems to me to have been the act of a madman. Unless, indeed, he was cunning enough to foresee that this was exactly the appearance it would present, and was therefore the best defence he could put up against suspicion.
Further, of course Munting provided Lathom with a complete alibi for the whole of Saturday and an unprejudiced witness as to the discovery of the body. Suppose, for example, that Harrison, instead of having been dead six or seven hours, had been only just dead or on the point of expiring when they got there, Munting could have given evidence that they had found him in that condition on their arrival.
On the other hand, Lathom was running a very serious risk, not only of defeating his own ends, but of having the whole vile plot exposed. If they had found Harrison still alive, they would have had no choice but to summon a doctor immediately; the victim might have recovered, or at least recovered sufficiently to denounce Lathom.
Note: Is Munting entirely cleared from complicity in the murder? His behaviour has been suspicious, and he has withheld information as long as possible. Not to trust him too far.
Neither Munting nor his wife seem to find as much difficulty as I do about this part of the business. They agree that a man of Lathom’s temperament, having committed a murder, would be afraid to be alone, and would take any risks to secure companionship. They instance Patrick Mahon’s incredible rashness in taking Miss Duncan to sleep at the Crumbles on the very night after he had murdered Emily Kaye, and while her dead body was actually lying in the next room. These people are both novelists and are supposed to have studied human nature. They say it is full of inconsistencies and I daresay they are right. I admit that, to me, the mentality of men like Lathom is perfectly incomprehensible, and I am ready to believe anything.
It was late when I left the Muntings, taking away with me the letters they gave me, and having obtained from Munting a promise that he would draw up a statement of the course of events during the periods not covered by the letters, and containing, in particular, an exact account of what took place at ‘The Shack’. This is the statement which forms part of this dossier, divided into chronological sections for greater ease of reference. I regret that it is so diffuse and adorned with so many unnecessary personal reflections and literary embellishments. It seems that the vanity of writers must be indulged at all costs, even where a straightforward summary of events would be far more useful. I have not, however, ventured to omit or alter anything, preferring to submit the documents exactly as they stand.
My next step was to write to Sir James Lubbock, raising the various points noted in the schedule for his consideration. In the course of a few days I received the following courteous reply.
Home Office 12 January, 1930
Paul Harrison, Esq.
Dear Sir,
I have your letter of inquiry with regard to the circumstances attending your late father’s unfortunate death. I quite understand that you are anxious to have the fullest information about it, and will do my best to clear up the various points you raise.
You may rest fully assured that the death was in fact due to the cause stated at the inquest, viz.: poisoning by muscarine, the poisonous principle of the fungus Amanita muscaria. In such a case I should not confine myself to searching for the particular poison suggested by the circumstances, but should search, as a matter of routine, for all the various classes of scheduled poisons, including not only the other vegetable alkalis but also the metallic poisons. The analysis was made with great care, and I can confidently state that every possibility was eliminated, except that of poisoning by muscarine. This poison, which was present in very considerable quantities, was unmistakably identified, while the symptoms and post-mortem appearances, as reported by the witnesses, were indubitably consistent with this form of poisoning.
I may add that preparations of the viscera, vomit, etc., and the unconsumed part of the dish of fungi have been preserved untouched, as is my invariable custom in such cases, so as to be available for future reference or analysis in case of any further question being raised. Humanly speaking, however, you may rely absolutely on the accuracy of my results.
