The Confidence-Man. His Masquerade

Herman Melville

A post-modern masterpiece; a century ahead of its time. The novel portrays a Canterbury Tales-style group of steamboat passengers whose interlocking stories are told as they travel down the Mississippi River toward New Orleans. The novel is written as cultural satire, allegory, and metaphysical treatise, dealing with themes of sincerity, identity, morality, religiosity, economic materialism, irony, and cynicism. And the novel itself tests the confidence of the reader as each character slides away beneath the muddy prose waters of the river. Melville introduces characters who change identities so rapidly that the reader is confronted with a portrait of the American frontier as perceived through a series of disguises.

Cleek. The Master Detective

Thomas W. Hanshew

Collection of several short mysteries, starring consulting detective Hamilton Cleek and his incredible skills at disguise with the assistance of his cockney assistant Dollops. Cleek is poacher-turned-gamekeeper, a master criminal who decides to turn straight and work for Scotland Yard after being stricken by the sight of a lovely, innocent young woman whose jewels he was about to pinch. Told as a fairly continuous narrative, held together by the underlying thread of Cleeks efforts to redeem himself and thus gain the affection of the woman with whom he has fallen in love. There is also another underlying thread concerning Cleeks erstwhile accomplice, Margot, and her present accomplice, Merode, as Cleek occasionally finds himself foiling their plans. Each one of these stories is a romp, some more successful than others.

O krakowskich psach i kleparskich kotach - Polskie miasta w baśni i legendzie

Barbara Tylicka

Książka zawiera 34 legendy o wszystkich polskich miastach wojewódzkich i kilku mniejszych ośrodkach. Wybór uwzględnia legendy dotyczące etymologii nazw i ważne wydarzenia historyczne. Każde hasło opatrzone jest herbem, na wyklejce jest mapa Polski z zaznaczonymi opisywanymi miastami. Książkę zamyka słowniczek i bibliografia. Narodziny miast giną w mrokach dziejów. Zwykliśmy je nazywać bajecznymi, legendarnymi. Archeolodzy dopiero od XIX wieku świadomie drążą ziemię, odkrywając tajemnice zagubionych cywilizacji. Wykopaliska poświadczają, że źródłem rozwoju cywilizacji, kultury i nauki od tysięcy lat były miasta. To one wypowiadały wojny, zawierały pokój, stawały się łupem grabieżców, ginęły od zarazy i klęsk żywiołowych. O ich mieszkańcach, budowlach i wydarzeniach krążyły ustnie przekazywane wieści, powtarzane przez pokolenia. Razem z miastem rosła jego legenda. Historyczne fakty, autentyczne doświadczenia w opowieściach ludowych mieszały się z marzeniami i sposobem widzenia opowiadaczy. Mówiona literatura ludowa, spisana potem przez uczonych etnografów i ludowych twórców, ciągle jest przedmiotem literackich opracowań pisarzy, poetów, źródłem legend i baśni. (...)

The Thief in the Night

Edgar Wallace

Edgar Wallace (1875-1932) was a publishing phenomenon in his day, his name being synonymous with the word thriller, a genre some would credit him with inventing. His popularity at the time was comparable to that of Charles Dickens one of Wallaces publishers claimed that a quarter of all books read in England were written by him. The Thief in the Night is an enjoyable easy going, fast moving mystery novella, set in England during the 1928s. Diamond plaques are being stolen from wealthy girls and poison pen letters are being delivered Inspector Jack Danton is puzzled... Wonderful entertainment and highly entertaining. If you havent discovered the joys of Wallaces thrillers there is a good place to start. Highly recommended.

The Hidden Secrets: Late Byzantium in the Western and Polish Context

Małgorzata Dąbrowska

Professor Małgorzata Dąbrowska, a distinguished scholar dealing with the history of Byzantium in the Middle Ages, belongs to the few Byzantinists who have become internationally acclaimed. A considerable part of her output concerns Polish-Byzantine relations which are hardly known to foreign scholars because of the language barrier, and yet they attract the interest of scholars all over the world as a new aspect of Byzantine studies. The publication of English and French works by Małgorzata Dąbrowska will thus facilitate better understanding between the Latin and Orthodox milieux in the European world. The author’s style is absolutely superb, regardless of the fact whether her texts are written in Polish or in other languages. This adds another quality to her oeuvre. From the review by Professor Maciej Salamon   Professor Małgorzata Dąbrowska holds a special place among the Polish Byzantinists as an outstanding specialist in the history of late Byzantium and its relations with Europe (including Poland, which is, undoubtedly, worth attention). The current collection of articles can be seen as a detailed sequel to the author’s monographs Byzantium, France and the Holy See in the Second Half of the 13th Century and The Latin Ladies on the Bosporos. Byzantine­Latin Marriages in the Imperial Family of the Palaiologoi (13th-15th Centuries). Both titles reflect faithfully the author’s favourite and interrelated subjects of study, namely the relations between Byzantium and western Europe, especially the matrimonial policy, which is handled in a detailed and innovative way.
