Thank goodness for another fairly easy one. I needed a break from A72V2 where I seem to have ground to a halt and although I haven't yet given up.
I liked the way that one theme kept repeating itself in the way that I solved it.
Probably about the same level as A72 so I'll rate this as 1.0.
Here is my walkthrough for A73, posted in the "wee sma' hours" again so I'll check it as soon as I can and tidy it up then; I know that I've missed so clean-ups in the later stages so may be able to make it a bit shorter. I look forward to the clocks going back so that will give Frank and I an extra hour to try to solve Assassins on Thursdays.
Edit. I've now checked my walkthrough and added the final steps that it was too late for last night. I found that I'd been getting careless and missing some clean-ups as early as step 23, which meant that I could insert an extra step shortly after that, so I've just replaced the whole walkthrough rather than editing specific steps.

Re: assassin 73
Yes,a pretty straightforward one and no combo crunching required.Here's an outline of how I solved it.
1. I-O c1-4 -> r2c4=r5c5+1
2. I-O c6-9 -> r6c6=r4c5+2
3. r4c456=8={134}
Together with 29(4) cage N5 can easily complete N5 as
431
269
785
4. Also r5c3=8 and r7c5=9 r5c12={45}
5. r9c3<>9
6. I N7=12
7. I c12-> r2378=26 <> 1... and r28c3=9 <> {18}
8. Thus 1 in N7 is at r7c13,r9c3.
9. But cannot be 1 at r7c1 as both options {129} and {138} blocked.
The clincher... both remaining options for the 1 in N7 -> R7C1=8.
as the [129} option is blocked and 1 at r7c3->2 at r6c3 and {13} r6c12
10. r7c1=8 -> r6c12={13} and r6c3=2
11. r3c1 now must=1 no other option so 10(3) cage N1={235} -> r4c12={67}
12.8 In n1 is at r23c2
13. The second clincher... the 58 pairs in both N1 and N4 (and not at r34c3)
-> the 22(3) cage N124 <> 9{58} therefore = {967}
14. From 11. above -> r4c3=9 r3c4=6 r3c3=7 r1c3=6
Now just a mop up.
Another very nice killer..thanks Ruud

1. I-O c1-4 -> r2c4=r5c5+1

Together with 29(4) cage N5 can easily complete N5 as

4. Also r5c3=8 and r7c5=9 r5c12={45}
5. r9c3<>9
6. I N7=12
7. I c12-> r2378=26 <> 1... and r28c3=9 <> {18}
8. Thus 1 in N7 is at r7c13,r9c3.
9. But cannot be 1 at r7c1 as both options {129} and {138} blocked.

11. r3c1 now must=1 no other option so 10(3) cage N1={235} -> r4c12={67}
12.8 In n1 is at r23c2
13. The second clincher... the 58 pairs in both N1 and N4 (and not at r34c3)
-> the 22(3) cage N124 <> 9{58} therefore = {967}
14. From 11. above -> r4c3=9 r3c4=6 r3c3=7 r1c3=6
Now just a mop up.

Although this Assassin was "just" of rating 1.0 it kept me busy all day long but it was more my fault since I messed up my walkthrough couple a times so that I hit a dead end.
I used pretty much the same trick as Cathy though without the outies of N5. And Ruud was right about the length of the walkthrough. After the first steps I thought the Assassin was finished but guess I was wrong or maybe my mop-up is not the shortest way.
