"To begin with — that he had a tabular mind. His crimes were listed by alphabetical progression — that was obviously important to him. On the other hand, he had no particular taste in victims — Mrs. Ascher, Betty Barnard, Sir Carmichael Clarke, they all differed widely from each other. There was no sex complex — no particular age complex, and that seemed to me to be a very curious fact.
If a man kills indiscriminately it is usually because he removes anyone who stands in his way or annoys him. But the alphabetical progression showed that such was not the case here. The other type of killer usually selects a particular type of victim — nearly always of the opposite sex. There was something haphazard about the procedure of A.B.C. that seemed to me to be at war with the alphabetical selection."
"The slight inferences I permitted myself to make
inference ['Inf(@)r(@)ns], undeveloped ['VndI'vel@pt], predominate [prI'dOmIneIt]
"The slight inferences I permitted myself to make. The choice of the A.B.C. suggested to me what I may call a railway-minded man. This is more common in men than women. Small boys love trains better than small girls do. It might be the sign, too, of an in some ways undeveloped mind. The 'boy' motif still predominated."
"The death of Betty Barnard
suggestive [s@'dZestIv], term [t@:m], character ['k&r@kt@]
"The death of Betty Barnard and the manner of it gave me certain other indications. The manner of her death was particularly suggestive. (Forgive me, Mr. Fraser.) To begin with, she was strangled with her own belt — therefore she must almost certainly have been killed by someone with whom she was on friendly or affectionate terms. When I learnt something of her character a picture grew up in my mind."
