Parker pulled at his pipe for a few minutes.
“There’s something in that,” he said finally. “I think perhaps it’s worth while putting it before the authorities. But we mustn’t be in too much of a hurry, you know. I wish we were further ahead with our other proofs. There’s such a thing as Habeas Corpus—you can’t hold on to people indefinitely just on a charge of stealing coal—”
“There’s the breaking and entering, don’t forget that. It’s burglary, after all. You can get penal servitude for life for burglary.”
“But it all depends on the view the law takes of the coal. It might decide that there was no original intention of stealing coal, and treat the thing as a mere misdemeanour or civil trespass. Anyhow, we don’t really want a conviction for stealing coal. But I’ll see what they think about it at our place, and meanwhile I’ll get hold of Trigg again and try and find the taxi-driver. And Trigg’s doctor. We might get it as an attempt to murder Trigg, or at least to inflict grievous bodily harm. But I should like some more evidence about—”
“Cuckoo! So should I. But I can’t manufacture evidence out of nothing. Dash it all, be reasonable. I’ve built you up a case out of nothing. Isn’t that handsome enough? Base ingratitude—that’s what’s the matter with you.”
Parker’s inquiries took some time, and June lingered into its longest days.
Chamberlin and Levine flew the Atlantic, and Segrave bade farewell to Brooklands. The Daily Yell wrote anti-Red leaders and discovered a plot, somebody laid claim to a marquisate, and a Czecho-Slovakian pretended to swim the Channel. Hammond out-graced Grace, there was an outburst of murder at Moscow, Foxlaw won the Gold Cup and the earth opened at Oxhey and swallowed up somebody’s front garden. Oxford decided that women were dangerous, and the electric hare consented to run at the White City. England’s supremacy was challenged at Wimbledon, and the House of Lords made the gesture of stooping to conquer.
Meanwhile, Lord Peter’s projected magnum opus on a-hundred-and-one ways of causing sudden death had advanced by the accumulation of a mass of notes which flowed all over the library at the flat, and threatened to engulf Bunter, whose task it was to file and cross-reference and generally to produce order from chaos. Oriental scholars and explorers were button-holed in clubs and strenuously pumped on the subject of abstruse native poisons; horrid experiments performed in German laboratories were communicated in unreadable documents; and the life of Sir James Lubbock, who had the misfortune to be a particular friend of Lord Peter’s, was made a burden to him with daily inquiries as to the post-mortem detection of such varying substances as chloroform, curate, hydrocyanic acid gas and diethylsulphonmethylethylmetane.
“But surely there must be something which kills without leaving a trace,” pleaded Lord Peter, when at length informed that the persecution must cease. “A thing in such universal demand—surely it is not beyond the wit of scientists to invent it. It must exist. Why isn’t it properly advertised? There ought to be a company to exploit it. It’s simply ridiculous. Why, it’s a thing one might be wantin’ one’s self any day.”
“You don’t understand,” said Sir James Lubbock. “Plenty of poisons leave no particular post-mortem appearances. And plenty of them—especially the vegetable ones—are difficult to find by analysis, unless you know what you are looking for. For instance, if you’re testing for arsenic, that test won’t tell you whether strychnine is present or not. And if you’re testing for strychnine, you won’t find morphia. You’ve got to try one test after another till you hit the right one. And of course there are certain poisons for which no recognised tests exist.”
