In one of his letters Ernst represented himself as "a zealous stamp collector," of course to explain, in the event of detection, the constant remittances he was receiving from Germany. This letter, addressed to "Miss Reimers," ran:-- Dear Mr. Steinhauer,--Best thanks for the 100 marks, which were handed to me mid-day to-day. If you think it right you can in future send my advance direct to me without having recourse to a third person--namely, in the following way. I am a zealous stamp collector. Many of my customers and also my assistants know this. On the occasion of the next remittance copy the following letter:-- "Dear Mr. Ernst,--Your last parcel of stamps arrived just in time to be included in last month's sale. Messrs. Kurt Moeser and also Koehler, the Berlin stamp auctioneers, are realising good prices at their sales. I have enclosed 100 marks on account, and will forward balance later. A receipt for the enclosed by return will oblige." I have sent you last Sunday's paper. What I can see from the case Henschel will go over to the British Secret Service just as the doctor from Glasgow has done. It has also occurred to me that Henschel's wife's maiden name was Miss Riley, and that one of Scotland Yard's Special Service Inspectors, who had the case in hand, was also called Riley. In conclusion, many greetings.--I remain, yours, J. Walters. It may be mentioned incidentally that the "doctor from Glasgow" was Armgaard Carl Graves, a well-known spy. Henschel was a German who was accused in London on his own confession of disclosing naval secrets and of conspiring with the ex-gunner Parrott. It was suggested that certain information he gave was communicated under the understanding that he should not be prosecuted, and under the circumstances the Crown withdrew the case, the accused giving an undertaking that he would not in any way make known the matter with which he had become acquainted. Ernst's case was hopeless from the start; in fact, so complete was the evidence, that as soon as Mr. Bodkin had opened the case for the Crown, his counsel withdrew, explaining that the prisoner had assured him he had had nothing to do with espionage, but that he (counsel) was sure Mr. Bodkin would not make an opening statement he could not justify. Ernst was sent to seven years' penal servitude. "You are a mean, mercenary spy," said Mr. Justice Coleridge in sentencing him, "ready to betray your country to the enemy for money; equally ready, I dare say, to betray Germany to us for an increased reward." The case could not have been better summed up.
