Character Testimonals

By Laszlo Kreizler

Dr Kreizler first meets the Isaacson brothers during The Alienist investigation and although he initially finds them perplexing, he grows to have a high admiration for their abilities as police officers and scientists. In return, they have a very high respect for him (particularly Lucius who seems to look up to him as a role model) and they become good friends.

The Alienist, 105:

We went upstairs, and as I fetched my coat from the consultation room, Laszlo continued to look intrigued. "There's no doubting they're idiosyncratic," he said as he walked me to the front door. "But I've a feeling they know their work. [...]"

By John Moore

Like Dr Kreizler, John first meets the Isaacson brothers within The Alienist and as with Kreizler, although he initially feels some reservation about the odd pair, he grows to enjoy their comical way and he, too, has a high respect for their abilities.

The Alienist, 152:

Whatever reservations Kreizler, Sara, and I had had about the Isaacsons' peculiar personal behaviour, their work far outweighted such considerations [...]

By Stevie Taggert

Stevie isn't particularly close to the Isaacson brothers but they do enjoy each others company and, like everyone else in the investigative team, Stevie has a high respect for their talents.

The Angel of Darkness, 49:

There weren't two better detectives in all the world than the Isaacsons, they'd proved that much during the Beecham case: trained in medicine and law in addition to criminal science, they kept up with advances in tracking theories and techniques from every corner of the world. It was their knowledge of the still unaccepted science of fingerprinting, for instance, that'd put the first crack in the Beecham case. They had an arsenal of cameras, chemicals, and microscopes that they brought to bear on any problem what might seem totally incomprehensible to your average detective; but they did love to bicker,a nd most of the time they went at it like a couple of old hens.
