"It will have blood; they say, blood will have blood"—
i.e., Queen Elizabeth, being a person of good blood, or high lineage, will have blood, i.e., from the head of the person she beats with the crutch.
A few lines further on is a striking confirmation of this.
Macbeth says,—
"How say'st thou, that Macduff denies his person
At our great bidding?"
Macduff here is cryptographic for Shakspeare. When summoned by the Queen to answer Cecil's charge, Shakspeare did deny his person at her bidding. Mr. Donnelly's is a great discovery. The world does advance, in spite of Lord Salisbury. Yours, Radical.
Dear Sir,—How long will the British public allow an impudent Yankee to lead it astray? Mr. Donnelly has evidently never read my historical novel, A Tale of the Invincible Armada, which somehow failed to meet with the enthusiasm it deserved, or he would know that Cecil valued Shakspeare most highly. In my book he never addresses the Bard without saying, "Marry, Gossip," or "I' faith, good coz." I am sure your readers will be glad of this information; also to hear that I am bringing out a cheap popular edition of the same book, price only three-and-sixpence. Order at once, Yours, M. Ainchance.
Sir,—Perhaps, after all, the best solution of the Shakspeare-Bacon puzzle is one analogous to that suggested by a learned Don in the Homer controversy—viz., that the person who wrote the plays was not Shakspeare, but another man of the same name. Yours, Commonsensicus Academicus.
