Shoplet

[…] that shoplet so obscurely placed amid other dark-browed houses […]

""At the Sign of the Jack-o'-Lantern" sounds like the name of a Hallowe'en comedietta, or perhaps of an arts-and-crafts shoplet […]

[…] to me it was encouragingly romantic to be recommended to a remailleuse […] whose shoplet was "en face de la Tour de Charlemagne, Madame."

[…] so long as he left 1 m 20 between the shoplet and his premises he has complied with the scheme's provisions.
