"When a seed-merchant of cautious disposition and an eye to the main chance receives from an eminent firm of jam-manufacturers an extremely large order for clover-seed, his emotions are mixed. Joy may be said to predominate, but with the joy comes also uncertainty. Are these people, he asks himself, proposing to set up as farmers of a large scale, or do they merely want the seed to give verisimilitude to their otherwise bald and unconvincing raspberry jam? On the solution of this problem depends the important matter of price, for, obviously, you can charge a fraudulent jam disseminator in a manner which an honest farmer would resent. This was the problem which was furrowing the brow of Mr. Julian Fineberg, of Bury St. Edwards, one sunny morning when Roland Bleke knocked at his door; and such was its difficulty that only at the nineteenth knock did Mr. Fineberg raise his head."
