The Blue Scarab

Medico-legal practice is largely concerned with crimes against the person, the details of which are often sordid, gruesome and unpleasant. Hence the curious and romantic case of the Blue Scarab (though really outside our specialty) came as somewhat of a relief. But to me it is of interest principally as illustrating two of those remarkable gifts which made my friend, Thorndyke, unique as an investigator: his uncanny power of picking out the one essential fact at a glance, and his capacity to produce, when required, inexhaustible stores of unexpected knowledge of the most out-of-the-way subjects.

It was late in the afternoon when Mr. James Blowgrave arrived, by appointment, at our chambers, accompanied by his daughter, a rather strikingly pretty girl of about twenty-two; and when we had mutually introduced ourselves, the consultation began without preamble.

“I didn’t give any details in my letter to you,” said Mr. Blowgrave. “I thought it better not to, for fear you might decline the case. It is really a matter of a robbery, but not quite an ordinary robbery. There are some unusual and rather mysterious features in the case. And as the police hold out very little hope, I have come to ask if you will give me your opinion on the case and perhaps look into it for me. But first I had better tell you how the affair happened.

“The robbery occurred just a fortnight ago, about half-past nine o’clock in the evening. I was sitting in my study with my daughter, looking over some things that I had taken from a small deed-box, when a servant rushed in to tell us that one of the outbuildings was on fire. Now my study opens by a French window on the garden at the back, and, as the outbuilding was in a meadow at the side of the garden, I went out that way, leaving the French window open; but before going I hastily put the things back in the deed-box and locked it.

“The building—which I used partly as a lumber store and partly as a workshop—was well alight and the whole household was already on the spot, the boy working the pump and the two maids carrying the buckets and throwing water on the fire. My daughter and I joined the party and helped to carry the buckets and take out what goods we could reach from the burning building. But it was nearly half an hour before we got the fire completely extinguished, and then my daughter and I went to our rooms to wash and tidy ourselves up. We returned to the study together, and when I had shut the French window my daughter proposed that we should resume our interrupted occupation. Thereupon I took out of my pocket the key of the deed-box and turned to the cabinet on which the box always stood.

“But there was no deed-box there!

“For a moment I thought I must have moved it, and cast my eyes round the room in search of it. But it was nowhere to be seen, and a moment’s reflection reminded me that I had left it in its usual place. The only possible conclusion was that during our absence at the fire, somebody must have come in by the window and taken it. And it looked as if that somebody had deliberately set fire to the outbuilding for the express purpose of luring us all out of the house.”

“That is what the appearances suggest,” Thorndyke agreed. “Is the study window furnished with a blind or curtains?”

“Curtains,” replied Mr. Blowgrave. “But they were not drawn. Any one in the garden could have seen into the room; and the garden is easily accessible to an active person who could climb over a low wall.”

“So far, then,” said Thorndyke, “the robbery might be the work of a casual prowler who had got into the garden and watched you through the window, and assuming that the things you had taken from the box were of value, seized an easy opportunity to make off with them. Were the things of any considerable value?”

“To a thief they were of no value at all. There were a number of share certificates, a lease, one or two agreements, some family photographs and a small box containing an old letter and a scarab. Nothing worth stealing, you see, for the certificates were made out in my name and were therefore unnegotiable.”

“And the scarab?”

“That may have been lapis lazuli, but more probably it was a blue glass imitation. In any case it was of no considerable value. It was about an inch and a half long. But before you come to any conclusion, I had better finish the story. The robbery was on Tuesday, the 7th of June. I gave information to the police, with a description of the missing property, but nothing happened until Wednesday, the 15th, when I received a registered parcel bearing the Southampton postmark. On opening it I found, to my astonishment, the entire contents of the deed-box, with the exception of the scarab, and this rather mysterious communication.”

He took from his pocket-book and handed to Thorndyke an ordinary envelope addressed in typewritten characters, and sealed with a large, elliptical seal, the face of which was covered with minute hieroglyphics.

“This,” said Thorndyke, “I take to be an impression of the scarab; and an excellent impression it is.”

“Yes,” replied Mr. Blowgrave, “I have no doubt that it is the scarab. It is about the same size.”

Thorndyke looked quickly at our client with an expression of surprise. “But,” he asked, “don’t you recognize the hieroglyphics on it?”

Mr. Blowgrave smiled deprecatingly. “The fact is,” said he, “I don’t know anything about hieroglyphics, but I should say, as far as I can judge, these look the same. What do you think, Nellie?”

Miss Blowgrave looked at the seal—rather vaguely—and replied, “I am in the same position. Hieroglyphics are to me just funny-looking things that don’t mean anything. But these look the same to me as those on our scarab, though I expect any other hieroglyphics would, for that matter.”

Thorndyke made no comment on this statement, but examined the seal attentively through his lens. Then he drew out the contents of the envelope, consisting of two letters, one typewritten and the other in a faded brown handwriting. The former he read through and then inspected the paper closely, holding it up to the light to observe the watermark.
