“The Peveril again!”
“Yes. I recognise the hand of Mr. Trigg’s mysterious charmer. The Rev. Hallelujah Dawson’s card, with message ‘Please give parcel to bearer,’ was presented by a District Messenger next day, with a verbal explanation that the gentleman found he could not get up to Town after all. The messenger, obeying instructions received by telephone, took the parcel to a lady in a nurse’s dress on the platform at Charing Cross. Asked to describe the lady, he said she was tall and wore blue glasses and the usual cloak and bonnet. So that’s that.”
“How were the goods paid for?”
“Postal order, purchased at the West Central office at the busiest moment of the day.”
“And when did all this happen?”
“That’s the most interesting part of the business. Last month, shortly before Miss Whittaker and Miss Findlater returned from Kent. This plot was well thought out beforehand.”
“Yes. Well, that’s something more for you to pin on to Mrs. Forrest. It looks like proof of conspiracy, but whether it’s proof of murder—”
“It’s meant to look like a conspiracy of Cousin Hallelujah’s, I suppose. Oh, well, we shall have to trace the letters and the typewriter that wrote them and interrogate all these people, I suppose. God! what a grind! Hullo! Come in! Oh, it’s you, doctor?”
“Excuse my interrupting your breakfast,” said Dr. Faulkner, “but early this morning, while lying awake, I was visited with a bright idea. So I had to come and work it off on you while it was fresh. About the blow on the head and the marks on the arms, you know. Do you suppose they served a double purpose? Besides making it look like the work of a gang, could they be hiding some other, smaller mark? Poison, for instance, could be injected, and the mark covered up by scratches and cuts inflicted after death.”
“Frankly,” said Parker, “I wish I could think it. It’s a very sound idea and may be the right one. Our trouble is, that in the two previous deaths which we have been investigating, and which we are inclined to think form a part of the same series as this one, there have been no signs or traces of poison discoverable in the bodies at all by any examination or analysis that skill can devise. In fact, not only no proof of poison, but no proof of anything but natural death.”
