Henry Brodribb Irving (1879-1919) was an English stage actor, lawyer and historian who published two books of studies of infamous criminals. In a "Preface" to "A Book of Remarkable Criminals" he relates an anecdote that should be a forewarning to all viewers who start reading it:
"I remember my father telling me that sitting up late one night talking with Tennyson, the latter remarked that he had not kept such late hours since a recent visit of Jowett. On that occasion the poet and the philosopher had talked together well into the small hours of the morning. My father asked Tennyson what was the subject of conversation that had so engrossed them. 'Murders,' replied Tennyson."
