Aubrey Dexter

From UNION JACK issue 998, (1922):

It is a considerable while since an exploit of that "Raffles" of real life, AUBREY DEXTER, appeared in the pages of the UNION JACK — and for a very excellent reason.

Dexter, drawling of manner, almost a dude in appearance, yet, under his easy-going, almost foppish mask, a man of indomitable will, iron nerve, and reckless bravery, long ago proved himself a master among cracksmen; but, in 1917, owing to the energies of Sexton Blake, his adventurous career received a check. The famous criminal investigator of Baker Street sent him to the Old Bailey, where he received a sentence he completed only some twelve to eighteen months prior to the opening of the story which makes its appearance in the present number.

This was after Dexter had taken part in an audacious gold-mining swindle out in Brazil, a fraud which involved a sensational law-suit in the Chancery Division of the London Law Courts. The appearance of one of the witnesses in this case was considered of such high importance that his life was insured for no less a sum the £20,000, and, for that reason, in Sexton Blake's reference books, the affair is indexed under the heading of the "PROBLEM OF THE £20,000 WITNESS." (See UNION JACK No. 716 — June 30th, 1917.)

Dexter believed that he had the laugh of Sexton Blake because he was on Brazilian soil, and neither Blake nor Detective-Inspector Martin, of Scotland Yard, who was with him, held extradition warrants for him. But, Sexton Blake trumped Dexter's ace when he enticed the prince of cracksmen aboard a British vessel. By law, Dexter was then counted to be on British soil, and before he knew where he was, he found handcuffs clapped upon his wrists.

Aubrey Dexter was the son of respectable, law-abiding parents, who gave him a Public School and University education, so that it was not environment that caused him to go wrong. What then was the cause of his slipping into doings not countenanced by the Law? Probably a passion for excitement out of the usual, which made him find delight in the thrill of stealing into another man's house by the dead of night.

At all events, as has been said above, Dexter long since convinced public and police alike that he was a cracksman second to none. One of his most amazing feats was when he opened a combination safe by means of pressing the rubber sounder of an ordinary doctor's stethoscope against the steel door in the region of the lock, by which means his acute ears could distinguish the sound of the tumblers falling as he twisted at the pointer. When Sexton Blake heard that he had gained a remission in his sentence for good conduct and was again at large, the detective predicted that it would not be long ere he again waged war against respectable society, and that London, and probably the whole civilised world, would soon be startled once more by the impudent daring of his exploits.
